Everybody are making Arduino clones. So I thought I should make THE smallest. I took smallest package atmega88 – 28qfn (5mm x 5mm). Routed smallest possible resonator and as much pads as i could fit on in.
The result – Smallest Arduino clone ever! Size is only 7.4mm x 7.4mm! Features include:
- Auto reset
- 4 analog channels
- 1 digital i/o
- one LED
- funny readme with BOM
It needs arduino bootloader for atmega88 like ottantotto bootloader, probably it needs some hacking too because the resonator is 8MHz not the Arduino regular 16MHz.
