Description
Gopher ARCADE is a keychain-sized ATTiny85 game console based on Armour Grade, there’s a whole world of game consoles based on ATTiny85. I wanted to make some modifications and also improve my PCB making skills, so I recreated it from scratch using KiCAD since there were no source files, only gerbers.

The ATtiny85, as you can guess from the name, is a small 8-bit MCU, with only 512 bytes (yes, bytes) of RAM and 8 KB of flash memory, but it packs a punch. There’s a good community and collection of games written in Arduino/C: https://github.com/andyhighnumber/Attiny-Arduino-Games but of course it’s much funnier (and easier) to write them with TinyGo. One cool feature, is that instead of soldering the chip directly to the board, you could put a DIP socket, carry some ATTiny85 each one with a different game and use them as cartridges!
