So I experiment a lot on breadboards and have a couple atmega168’s that i just throw on a breadboard and then just make all the connections to use it, but by the time I’m done I end up with almost half a standard breadboard gone, and a bunch of jumpers running all over, etc…
So I made a layout for about the smallest possible breadboard arduino one could make.
It’s .63"x1.3" uses a TQFP chip, has USB, and also has a regulated power supply and a ISCP header (not really needed but I use them), what it doesn’t have is a reset switch, I almost never use it, so I don’t find that It is needed, if you have to reset that bad, unplug it, it does have auto reset of course.
Also has power LED, pin 13 LED, RX/TX LEDs, all digital I/O and 8 analog in’s, 2 ground pins, and 1 VCC and 1 Vin, of course it’s all surface mount 0603 size.
So is there interest in this? I’d have them made via the open source propaganda service and then release all the source files on the forge
It would be better to offer it with out the pins in, then you could use it in a project and since it has a ISCP port you don’t have to even solder on the USB chip, you could prototype on one with the chip then for the final version just burn the HEX file with the ISCP and a programmer leaving the USB off for an even thinner board with less parts and less cost.
