its not the first one,
its not the most refined,
its not the slimmest,
but it has a small foot print
and it was cheap.
0,98" oled and ATMega32u4 from ebay for under 8€ (excl. a small perf board and some tac switches). I skipped the battery and the piezo speaker simply because i didnt have some in house.
34 x 49 x 10 mm
This for me, was just a proof of concept, i ordered more parts and allready got some ideas for future Arduboy clones.
- Arduboy inside a NES controller
- ... inside a credit card
- ... with a bigger screen
Very nice, I like the pro micro form factor very much, it's just the right size for most things. I wonder, have you considered adding a battery to it, so you can actually take it on the road?
big screen 3-4inch and meybe add potenciometer
