We have design a Nano Every that use ATmega4808 , it will be easy to develop for updi, and can use as the JTAG to UPDI Programmer.
But I think there will have some bug that we can check out, if you check any problem, please tell us.
But I think there will have some bug that we can check out,
Ok, I'll byte....wheres the bug?
Jim
Now we have test it that if you download some sketch that use Serial1 at tx1 pin too fast will occupy the UPDI communication serial port, than it can not download by jtag2updi.
So now we can only set Serial at D2(PA0) and D3(PA1).
The programmer chip is an ATmega328P? You know jtag2updi can fit on a ATmega88PB, saving about 50c of cost? It just needs to be recompiled. Or use an ATmega328PB, which is also much cheaper than the mega328P.
Could you post a pic of the backside of the board? You don't have any in your store, there are only frontside pics.
El Tangas, I think you should have bite of the Cake $$$ ;)
EDIT: typos
El Tangas, I think you should have bite of the of the Cake $$$ ;)
Lol, no, actually this is all according to plan. I just want cheap mega AVR-0 boards to appear (this one is still too much, about $7). That's why I'm giving free advice to cut costs ;)
edit: keep in mind that the ATmega4809 Curiosity Nano has better features (debugger) and is not that much expensive. So this price range is not quite there, yet. It should be <$4.
edit2: it just occurred to me: the mega328P can be replaced by a LGT8F328P, thus saving about $1 in costs, while increasing the incorporation of Chinese tech. See? Win-win.
well, 7$ for a chinese kit is quite a lot also...not to say its bad quality...but...

Exactly, needs to be cheaper.
@El Tangas,
Yes, it would be nice if the "Nano Every" gets cloned by the Chinese.
They just replaced the Atmel USB chip with a CH340 in the traditional Nano.
The ATmega328P bootloader remains the same.
The punter gets exactly the same operational behaviour with genuine or clone Nano.
They could replace the SAMD10 with a similar Chinese MCU to give exactly the same operational behaviour
A genuine ATmega4809 is always used. This would be their main BOM item.
I would guess that the Chinese would prefer to use a CH340 instead of the genuine Atmel SAMD10 chip for USB.
This would mean a different Bootloader and different Arduino IDE "board" description i.e. fail as a 100% clone.
David.
Hi, El Tangas.
This is the back picture.
Because we have invest in time to develop this product, it not use you code to develop because we use other MCU not AVR Series.
But it was including the shipping cost.
The shipping cost more than $2.
Thanks for the pic. So you managed to place all the components on one side.
we use other MCU not AVR Series.
Now I'm curious, may I ask which chip you use?
We have design a Nano Every that use ATmega4808
and then the OP say they dont use AVR. well, O_o
I think thats why people should stay away from these companies....
No, we are talking about the UPDI interface chip, not the main one. I thought it was a mega328P.
edit: It looks like the markings are scrubbed, maybe it's secret, I don't like secrets :(
No, we are talking about the UPDI interface chip, not the main one. I thought it was a mega328P.
Interesting...what should it be ?
Interesting...what should it be ?
It can be almost anything, I'm guessing they ported jtag2updi to whatever it is. The minimum requirements are about 8MHz speed (preferably able to execute 1 instruction per clock), 512 bytes RAM and 4KB ROM/flash.
I would bet 8051 or ARM core.
edit: OK, I'll take a guess -> Nuvoton N76E003AQ20
I don't care what USB chip they use. As long as it gives exactly the same operational behaviour
I don't like the idea of scrubbed chips. They can keep the USB firmware private to their own company. The 328P Nano clones do not publish the CH340 source code (even if trivial)
And yes, of course the innovative Chinese company deserve to be profitable.
The SAMD10 seems to have the same price as a mega4808. (which is slightly cheaper than the 4809)
David.
I don't care what USB chip they use. As long as it gives exactly the same operational behaviour
I agree. I'm just curious.
They are using 2 chips for the interface: a version of the CH340 as USB/serial bridge and a mystery MCU as serial/UPDI bridge.
The original Nano Every uses a single interface chip, a SAMD11. The SAMD11 has a USB peripheral, so an external USB/serial chip is not needed. However, since the SAMD11 is a 3.3V chip, it needs level shifters to interface with the mega480X. So in terms of design efficiency I'd say it's a toss.
Ideally, you would use a MCU with USB interface, but that runs at 5V (or at least has 5V tolerant pins) and is cheap (< 80 cents).
My apologies. I wrote SAMD10 from memory. The SAMD11 seems to be a similar cost.
Yes, I am sure that there are several ways to get USB-Serial with 5V tolerance. And if a Chinese company can produce a cheaper product it seems a good idea (tm).
The EVERY has a full 48kB of Flash for user applications.
If it had been a regular AVR + USB-Serial design, you lose 1kB for an Optiboot-style bootloader. e.g. ATmega4808 + CH340.
As far as I can see, the mega4809 + SAMD11 design has "UPDI programming" but no "debugging".
The world would be a better place if all electronics was 3.3V.
David.
Edit. Just ordered one from Thinary (AliExpress). I will see how well it compares with the genuine EVERY (that arrived promptly from Italy/Holland)
Edit. Just ordered one from Thinary. I will see how well it compares with the genuine EVERY (that arrived promptly from Italy/Holland)
David, Perfect...looking forward for your feedback
In an ideal world it will work exactly the same.
In the real world it might take 30 days to arrive. (if not longer)
AliExpress is a mystery. Recently orders have arrived in 8-9 days. Others take weeks. AliExpress pages change to random language even if you Sign In as a known English speaker/country customer.
David.
Lately my AliExpress orders have been arriving in about 2 weeks, which I consider good time.
Looking forward to your opinions on this clone 
They are using 2 chips for the interface: a version of the CH340 as USB/serial bridge and a mystery MCU as serial/UPDI bridge.
PIC18F24K50 - Microcontrollers and Processors
The target price of $0.80 for a single chip comes from this possible 2 chip solution: CH340E (about $0.30 each for 100 quantity) + ATTiny804 (about $0.50 each for 100 quantity).
The usual limiting factor for the MCU is SRAM (at least 512 bytes are needed).
Anyway, to avoid messing around with USB programming maybe the 2 chip solution is actually better.
The Thinary 4808 EVERY arrived this afternoon.
The Megaavr Arduino Core expects a 4809 but the "upload" finds a 4808.
So I added an extra section to boards.txt which adds -pATmega4808 to upload.extra_params

Sketches obviously build ok since they think it is a 4809
It seems to upload ok via -c jtag2updi as a 4808
However the sketch does not run.
@El Tangas,
Any ideas?
I will try an AS7 project later.
David.
Edit. I built a binary for ATmega4809 in AS7. It will upload via avrdude -c jtag2updi -p ATmega4808. It does not run after a successful upload and verify.

I will try tomorrow to debug with ATMEL-ICE and UPDI pin.
Hi, David.
You can use this Arduino IDE URL to download the ATmega4808 core.
You can also download the core at this site:
https://github.com/Thinary/ThinaryArduino/tree/master/Thinary-megaavr
However the sketch does not run.
@El Tangas,
Any ideas?
IDK. If the verify checks out, the program should run, I suppose. But Thinary doesn't use my jtag2updi version, so I can't be sure.
Also, I never tested jtag2updi with the Mega AVR-0 series, a bug is always possible.
edit: Ok, I opened the Arduino IDE and loaded the "blink" test sketch on a bare mega4809 (PDIP version), using my current version of jtag2updi (it's not released yet, but the only change is support for LGT8F328P boards). The programmer is a LGT8F328P board. I told the Arduino IDE this setup was a Nano Every.
It's working fine, but it's just a small program, a bigger one might fail especially one bigger than 32kB if there is some numeric bug, we never know...
Anyway, the Arduino IDE keeps writing fuses and erasing the whole chip at every upload cycle. I don't know if this is the best option... I wrote jtag2updi to erase only the pages that are written to speed up things and not stress the flash so much, but whatever...
Ah-ha. The 4808 board has completely different pins_arduino.h wiring to the regular EVERY.
I altered the wiring macros in my AS7 project to suit.
MCUFRIEND_kbv works very nicely in AS7 (uploading with ATMEL-ICE)
Of course the Arduino IDE handles different pins_arduino.h for variants just fine.
Serial does NOT work. And if you attempt to use it, you are liable to stop Arduino uploads.
However it can be recovered with regular AS7 projects and ATMEL-ICE.
I think that I will give up with this board for the moment.
From Thinary's point of view. There is little point in a board that does not "clone" the NANO-EVERY seamlessly.
If it works better and is a fraction of the EVERY price punters might ignore the EVERY and go for the Thinary-4808. Even if it means different Core in the IDE.
All the Chinese clone Unos, Nanos, Mega2560s, Dues, ... work very well in the IDE.
It is cheaper for Chinese to use CH340. The boards sell very cheaply (to Western customers)
It is certainly a good idea (tm) to improve the NANO-EVERY. And of course it should be profitable for them too.
It must be heart breaking to manufacture boards in the cut-throat Nano (328P) market.
David.
Recently, the manufacturer of the classic CH340G has introduced new models that don't need a crystal, the CH330N and CH340E, this means less space and probably less money.
For the UPDI interface, the clones could use a LGT8F328P running jtag2updi (upcoming version).
This 2 chip interface solution would cost about $0.50 ($0.25 each chip, TaoBao prices), if we add the cost of the mega4809 that would be a total of $1.50 in silicon. I'm sure the rest would cost less than $1 judging from the other stuff that comes from China. Therefore, manufacturing cost: $2.50.
Selling the whole thing (Nano Every drop-in clone) for $4 or so should still turn a reasonable profit, if it becomes very popular.
edit: problem is, the Nano Every is already quite cheap at €8, even if the clones cost 1/2 I'm not sure people would go for it.

How To Program A Really Cheap Microcontroller | Hackaday
The Nano Every apparently implements the USART bridge like this (I'm speculating since I don't own one, just observing what the IDE does):
Normally, the SAMD11 acts as a USB/serial bridge connected to the USART0 of the Mega4809. Before programming starts, the IDE sends a DTR pulse of 20 seconds (why so long?), that the SAMD11 interprets as a signal to enter programming mode, that is, instead of USB/USART0 bride, it becomes a USB/UPDI bridge.
I think I should try to implement this behaviour in future versions of jtag2updi.
... the IDE sends a DTR pulse of 20 seconds (why so long?)
It seems that the 20 seconds isn't required.
From david.prentice (Link):
Woo-Hoo. I have cracked it:
mode %COMPORT% baud=12 dtr=on > nul mode %COMPORT% baud=12 dtr=off > nul
Could it be that the DTR is asserted for the duration of the download?
Actually, manufacturing cost is $3.2, and $2.5 is shipping cost, and $0.5 is give for aliexpress. we only get $0.99 for it.
If we don't choose Registration packet shipping, it can do be $4.99.
Like this:
Go on. You sell regular 328P Nanos for £1.50 each in lots of 10. It is a cut-throat market.
Your NANO-328P has components on both sides of pcb. Your EVERY-4808 has components on one side.
A similar number of similar components. The 4808 may cost you more than 328P.
Personally, I think it is important that Chinese manufacturers should make a good profit.
Manufacturers and their agents can arrange economic delivery.
Yes. The EVERY-4808 arrived safely in 15 days in a plastic box. Ordered 22 August. Received 6 September.
The plastic box was unnecessary for a small pcb. The padded envelope was sufficient.
OTOH, shops that mail delicate TFT or LCD screens in plastic envelopes without any protection are unwise. They just get broken glass screens and unhappy customers. My apologies: YOUR packing is excellent.
The "bootloader" works fine until you upload a sketch with Serial class. Subsequent uploads fail.
Unfortunately most of my programs use the Serial class. After all, that is the whole point of a USB-Serial connection.
I possess an ATMEL-ICE but not all customers expect to use an external programmer.
I added this to programmers.txt
atmel_ice.name=Atmel-ICE (UPDI) atmel_ice.communication=usb atmel_ice.protocol=atmelice_updi atmel_ice.program.protocol=atmelice_updi atmel_ice.program.tool=avrdude atmel_ice.program.extra_params=-Pusb
This lets me upload sketches via the UPDI pin. And means that I can recover the "bootloader" by using the ATMEL-ICE to upload a non-Serial sketch e.g. Blinky.
The regular NANO-EVERY can use Serial painlessly. The UPDI pad is not accessible from the top of the pcb.
At least your EVERY-4808 can access UPDI from a header pin. (otherwise the board is rendered useless after the first upload)
It is quite nice that you get the whole 49152 bytes of Flash for applications.
But the design would have been a lot simpler with 512 byte bootloader and 48640 bytes of application. e.g. like NANO-328P has ATmega328P + CH340
Yes, I am sure there is a market for a ATmega4808 + CH340 board.
The regular Arduino design of MCU + USB-Serial chip means that the Serial is always available. (however the user mistreats the MCU)
David.
Actually, manufacturing cost is $3.2, and $2.5 is shipping cost, and $0.5 is give for aliexpress. we only get $0.99 for it.
Thanks for the info. The manufacturing cost is a bit higher than my estimate.

Yeah, the manufacturing cost of the Thinary board at least makes sense. But this for example: https://www.aliexpress.com/item/...
A LGT nano clone for $1.30 incl. delivery, how can it be possible?
I would take his figures with a pinch of salt.
Of course the manufacturing cost is high for small runs.
If the product is successful they would be making 1000s. Look at Nano-328 or BluePill-STM32F103
Likewise, AliExpress will have different rates.
But the 'suspect' figure is shipping. It costs the same to mail 10 boards as 1 board. Or even 100 boards.
There is little point in tracked shipping for low value packets.
I don't know about Portugal. But in the UK there are many "online shops" that claim to have UK warehouses.
In fact they probably import the items "just in time" with regular fast delivery from China.
The Ebay customer pays more less than for genuine UK stock but gets her packet faster than the "free postage" Chinese shop (8-58 days to UK).
I wish Thinary success. After all, they have designed the schematic, pcb and written the custom Arduino Core software.
David.
I don't know about Portugal. But in the UK there are many "online shops" that claim to have UK warehouses.
No such things around here, probably the size of the market doesn't justify it. Normally I buy "big ticket" items (well, actually anything over €20) from such warehouses, usually located in the UK, Germany or Italy.
For me the main advantage is that those sellers take care of customs taxes and VAT, I don't care how, it's their problem. What matters is that I buy from an EU store so that customs don't bother me.
Their BOM is more cheap than us, and if we packet only the paper bag, it will cost the less shipping.
You need to use our core file, because we change the Serial port to D2, D3.
Hi,
Does anybody know how to use Serial-USB on Thinary Nano Every? I am using AS7 + Atmel-ICE + UPDI. I use Visual Micro plug-in, so I can use Arduino-style commands like Serial.print etc. Programs are loading fine, debug works too, only on the Serial monitor is empty. USB from the computer is connected to micro-USB port on Thinary board. I can load programs also from Arduino IDE + Thinary Nano Every Core + JTAG2UPDI. Same result - Serial does not work. Is there anything that I should additionally initialize in the program? Can anybody help?
Andrej
According to this https://www.avrfreaks.net/commen... you are supposed to use their core.
Problem is, they don't tell you where to get it... I'm guessing it's here: https://github.com/Thinary/ThinaryArduino/releases
Thanks for the answer.
Yes, I am using their core, same in AS7 and Arduino IDE. Under Additional Boards Manager in Preferences: https://raw.githubusercontent.co... .
I guess it is latest version, since I loaded it a month ago. But Serial over USB does not work. I was searching the net, but so far I did not find a solution. Perhaps I should connect external USB adapter on another set of RX-TX pins and use Serial2 (hopefull that would work)? But I do not like that solution, also because I would like to run an existing program without additional external hardware, and I do not like to change much the program. The best would be if I can include some additional setttings - port exchanges- in the Setup.
Andrej
Well, maybe this board does not emulate the Every behaviour correctly. The programmer chip is supposed to pass the UART signals by default. Only when a DTR pulse is received, is it supposed to enter programming mode.
@ amla11
It looks as if Thinary have stopped selling those boards.
If you have an ATMEL-ICE or PicKit4 you can program (and debug) them easily via UPDI.
Using Serial is fairly painful. If you are using the Thinary board as a one-off, I can probably show you what to do.
If you want to do any development with a mega4809 it is wise to buy the Curiosity board.
And use a genuine Nano-Every as the final target.
It would be nice if the Chinese produced a cheap Nano with just a 4808/4809 and a CH340.
Or perhaps with the new AVR chip and a CH340.
Personally, I think that a 5V Nano board is crazy. Especially when God has intended all electronics to be 3.3V
David.
Especially when God has intended all electronics to be 3.3V
"Especially when God has intended all electronics to be 5V."
(And all too soon that may be 1.5V?)
(And all too soon that may be 1.5V?)
Well that's religion for ya.
Silicon CPU "cores" have run at low voltage for at least 40 years. The outside world accesses the core via the GPIO drivers.
The core will run at whatever voltage suits the manufacture, power, speed, ... requirements.
I suspect that the outside world will remain at 2.8V - 3.3V or at least be tolerant.
A lot of electronics is NOT tolerant of 5V.
David.
@david
thank you for the answer. You are right suggesting Curiosity or native Arduino Nano Every as best solution. But anyway, since Thinary is on my desk and debug & programming over UPDI works fine, I would appreciate if just in case you have any idea how to use Serial.print on USB on this board. Otherwise I will use it for some other experiments.
Just for the background: In this case the "Serial.print" were more or less just a "debug" & info tool. I was developing a multi-process RTOS in combination with FSM - finite state machine. The Debug-Wire on Arduino 328P did not work for me despite using the Atmel-ICE. The story about my Debug-Wire + Atmel ICE experiments finally left me quite a few Nano's and UNO's dead. Very likely the AS7 + Atm.ICE messed up those fuses & locks so much, that the boards appear to be dead now. I was suspecting even that my Atmel ICE is defective - it just did not work despite trying to debug "by the book". I also disconnected that capacitor C5 between the reset and DTR line. On another side, Serial.print as debug tool is not very useful when watching real-time processes where tick-time is 10 msec. In the old times we had HP logic analyser + tracer + disasembler it was a fun. But, sorry, that is another story. So I ended on a 4808.
Regards, Andrej
Since you have an ATMEL-ICE everything should work quite nicely. UPDI is much nicer than debugWIRE.
There is a trough-hole terminal for UPDI on the Thinary. The Nano-Every has a tiny SMD pad.
Mind you, debugWIRE works fine on genuine Uno (or clone with RESET-EN solder-bridge)
But only works if you hack a Nano (328P type). You must remove both 1k0 pullup and 100nF
I will dig out my Thinary. And see if I can remember what I did.
Incidentally, when did you buy your Thinary?
It looks like they sold a handful in Aug-Sep 2019 and then quietly dropped it.
David.
It seems Thinary Nano Every is still sold at: https://www.aliexpress.com/item/4000427291663.html?spm=a2g0s.9042311.0.0.6f624c4d6RRSRE . By reading the QR code you find a link to load Thinary Arduino IDE core.
Thanks about debugWire info, it has been a while ago my attempts, maybe this time more luck. I will risk another UNO. But as we said, UPDI on 4808 really works well.
Andrej
Thanks for the link.
9898 pieces available
It looks as if they manufactured a batch of 10000 in August 2019. And have sold 192 so far. Hence the attractive $4.89 price.
to United Kingdom via Cainiao Super Economy Global
Estimated Delivery: 30-50 days
Horrifies me. Mind you, Chinese packets generally take 8-18 days to get to the UK. You might have to wait 50 days for a "no delivery".
If you are buying several boards it is worth paying for tracked shipping.
David.
You can use regular Arduino Serial comms:
#if defined(__AVR_ATmega4808__) #define Serial Serial1 #endif
If you possess an ATMEL-ICE select Tool in Arduino IDE. e.g. Programmer: Atmel-ICE UPDI
Then you can Sketch->Upload via Programmer (ctl-shift-U)
In AS7.0 you build, debug, run via the UPDI interface. It works nicely.
Current versions of Adafruit_GFX library will not build on Thinary. GFX is no problem. It is all the other dross that Adafruit declares as "dependent"
Downgrade to v1.7.x
I am not sure what the Thinary "bootload problem" is. Avrdude bootload works fine with the genuine Nano-Every both from AS7.0 or Arduino IDE.
David.
It would be nice to have a feature in JTAG2UPDI that caused it to switch to some sort of Serial Passthough mode after you were done programming the chip, until some sort of signal were received that put it back into UPDI mode.
This is what the SAMD11 on the genuine "Every" does, except that it has USB on one side, whereas it'd be nice to have a defined method with serial on both sides. (heh. Rx/Tx/DTR on one side, Rx/Tx/UPDI on the other.) I assume that this is essentially what the Thinary board is doing with its mystery chip...
My Thinary has a N76E003AQ20 Nuvoton microcontroller, CH340E910 USB-Serial, ATmega4808 Atmel microcontroller. i.e. no "secret" chips.
Meanwhile the Mega4808 works quite nicely with ATMEL-ICE but obviously not as nicely as the Curiosity 4809.
El Tangas can probably explain how it works. And how to recover the bootloader functionality. After all, not everyone has an Atmel-Ice.
I still reckon that a regular Optiboot-style bootloader would just need one CH340 and one Mega4808. You would lose 512 bytes of Flash memory but Chinese could knock the boards out cheaply.
As far as I know, the SAMD10 on the genuine Nano-Every does nothing more than USB-Serial and USB-UPDI programming. The SAMD10 does NOT provide full UPDI debugging.
David.
@david,
The trick "#define Serial Serial1" really works on Thinary Atmega4808. Thankyou for the advice. Now programming, debugging and Serial.print in AS7 works with the help of UPDI and Atmel ICE. I haven't try the Arduino IDE yet.
I haven't try to restore and use the bootloader, but would be convenient too for programming, when you do not need debug.
best regards,
Andrej
Hi,
my previous message was somehow lost, so I am repeating.
The question is, has anyone suceedeed using LCD20x4 on Thinary Nano Every using I2C interface?
I connected A5 - SCL, A4 - SDA, as usual for Nano.
I am using AS7 + Visual Micro Plugin for Arduino.
Downloading and debugging via UPDI works. The program loops in Wire.c library, function lcd.init().
The sentence is line 327:
/* Arduino requires blocking function */
while(master_result == TWIM_RESULT_UNKNOWN) {}
Any idea?

Hi, everybody
I try to draw pinout of this board
Could you check it and tell me what's wrong? or what should be add
Timers, interrupts (but don't know its names and pinouts )
Well google says:
so I'd start by comparing to that perhaps?
EDIT: actually more comprehensive is:
I go to that from the very interesting thread at:
https://forum.arduino.cc/index.php?topic=644395.0
Note that the Arduino pin numbers will depend on the core being used, and may vary from implementation to implementation, as will the pins for peripherals that are selectable via the pin mux.
The port pin numbers are of course fixed, per the datasheet, as are power and programming pins.

I would only label pins with functions provided by your boards.txt file.
For example, you have Ain8-Ain12 in the diagram, but your boards.txt only maps A0-A7.
How can you see, the arduino original nano every has Atmega4909. But in this topick we discussed chinese board with Atmega 4808
These are different boards. That's why I am trying to figure out a Chinese craft.
Please read #53 and other messages in this thread.
Yes, the Thinary board works. The Arduino "Thinary" core has a few problems. It has never been updated. Look at the GitHub repository.
Thinary do not seem to respond to Issues or Pull Requests.
Note that the pin usage is very different to the genuine Nano-Every.
You can see the usage from the pins_arduino.h and variant.cpp files
It is probably worth the current $4.89 sale price if you know what you are going to do with it.
And it would help Thinary to recoup some of the cost of assembling their first batch of boards.
It is unlikely that they will ever be able to shift the whole batch unless the "Thinary Core" worked 100%.
So there is little point in making a nice graphic for the pinout.

Hi!
Testing your board with Arduino environment. One bug found in package_thinary_index.json file, which declares the architecture of the chip. It is declared as AVR whereas it should be MEGAAVR. It has effect on many thing. In addition to that you must override A.BUILD.ARCH build variable from AVR to MEGAAVR. Otherwise AVR libraries does not work. Also, since 4808 has only 3 timers, one must play some timer swapping game with certain libraries. 4809 based board worked without modifications. Anyway, it is just what it is.
Another issue is that for some reason PA1 (D3) pin does not go from HIGH (+5V) to LOW (0V), but it goes from +5V to +2.5V and from there it fades to +2.2V like it is draining some capacitor. I have LEDs in PA2, PA4-PA7 and these pins works correctly. The foil on the Nano Every board goes directly from pin to pin. The pin operates like it is analog pin in sort, but it is GPIO digital only pin. At least it should be. I have tested this with couple of boards, which are not attached to other electronics. Any ideas?
BTW. This is good board with way better design than similar Arduino board has. It is EMC hell.
