Hello All,

would anyone like some free (unpopulated) PCBs. They are useful to mount a Tiny 24, programming header, a couple of switches, I/O pins, battery/power. They are about 48mm x 25mm, but you can cut off the antenna to make them about half the size. Please have a look at the pics.

If you have any questions please ask them here, otherwise email me and request how many you'd like and I'll get them sent to you. Don't be shy I have a LOAD of them and would rather they were used than go to a landfill.

All the best
Dren

These are the connections on the 10 way header:

ISP:
1=MISO/PA5
2=+V
3=SCLK/PA4
4=MOSI/PA6
5=/RST/PB3
6=0v
I/O:
7=TP102/PB2
8=TP104/0v
9=TP107/PA7
10=TP106/PA3

What'd you goof up?

 

"We trained hard... but it seemed that every time we were beginning to form up into a team, we would be reorganized. I was to learn later in life that we tend to meet any new situation by reorganizing. And a wonderful method it can be of creating the illusion of progress while producing confusion, inefficiency and demoralization." Petronius Arbiter, approx. 2000 years ago.

LOL ! Strangely nothing. The reason I have them is due the action of an overkeen purchasing manager who, unknown to me (and against all common sense), ordered a few thousand of them BEFORE the customer came back with their latest changes.

If you want to use the original circuit you can transmit at either 916 or 433MHz, using a few mA, with our standard receiver, we can typically transmit over 20M. The RF path is fiddly and the components' secondary attributes can be quite critical, so if you want to play with that side, good luck, I am not an RF engineer.

Did your purchaser also over-order on the ATTiny 24s? They seem to be very rare right now...

Four legs good, two legs bad, three legs stable.

Actually yes they did, they ordered EVERYTHING ! But the Tinys were also used on the next iteration of the PCB so (sadly) they were not going spare.
