Has anyone used these...

It looks to be a neat way to work up an AVR prototype.

#1 Hardware Problem? https://www.avrfreaks.net/forum/...

#2 Hardware Problem? Read AVR042.

#3 All grounds are not created equal

#4 Have you proved your chip is running at xxMHz?

#5 "If you think you need floating point to solve the problem then you don't understand the problem. If you really do need floating point then you have a problem you do not understand."

Seems "OK,"  nowadays interest would be less, since many chips are not avail in DIP.  Would be MUCH nicer if the board included a serial converter section and maybe a couple of LEDS ready to jumper in and use. Otherwise the board doesn't offer too much (maybe the best is a nice area for the xtal---much better that the plugin protoboards).  However if this save you an hour or two, that's worth at least $8 cheeky

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!

Yes, they are high quality and well configured to interface with external devices.   I have used the uController board for the ATmega328, ATtiny84 and 681ATtiny for about five years now and have no problems with them.

 

His other boards at https://protostack.com.au/produc... are also great boards for one-off projects.

That's good to know. I've bough a few of the 28-pin boards and some medium sized prototype board.

Cute regulator layout!

This must be a challenging market place when you can buy 5 x pcb of your design from jlc for a few $s plus shipping.

No Double Sided board, nothing to me.

Protype first then JLPCB.

Sorry, Brian.

 

I used such boards in my projects, a couple of years only, then switched to Double Side, through-connected, they are confident, they are a law.

The original mentioned AVR board is double sided, plated holes.

Yes, the 2nd perfboard isn't as solid, lacking the plated holes (they don't seem present)---but it's still quite a nice build.

The current prototype boards on the website are double sided.

 

I should have mine by the end of the week and will post a report.

This is very popular for prototypes

DIP is very 90s smiley

Well, maybe, but until someone comes up with an affordable non-volatile memory with both SPI and parallel interfaces, if you need a part programmed off-board you have few options.

 

I'm currently working on a design which requires six eight-bit parallel roms of some flavour; an external DIP socket is an excellent solution. External ZIF sockets for SM parts exist, but you still really need to solder those parts to the target board after programming.

(Honeywell do one, actually, but it's a few hundred dollars per chip. That's not a solution unless you're in the space industry.)

Here,the PDIP are cheaper than SMD.

I'm now slightly to SMD cause the weight and size for board.
