So idea was an Arduino board, built specificaly for playing simple games, in the smallest form factor possible. As a teenager I knew it would be hard, considering the tools I have on my disposal, but I tried anyways - and failed lol.
I made schematics in Eagle, and boards were manufactured in China by JLCPCB.
Long story short, it does not function properly. Parts that DO work are circuit for OLED, and FTDI controler (FT230XS). Problem is in FTDI chip which is unable to properly upload the Arduino sketch to Atmega328, with Arduino bootloader. It is probably possible to program it by another Arduino compatible board but I have none laying around. So troubleshooting is gonna have to wait for when the school starts. As I don't own basic equipment for SMD soldering.
Nevertheless, I still felt a need to share it. I really like what finished board looks like, hope you do too, because its all you get with this one.
If you think you can help me with project please contact me somehow..
