The micro:bit is an impressive piece of hardware that packs a bunch of features onto a board that’s half the size of a credit card. Between the programmable buttons, the LEDs, the motion detection, and the BLE support, it has a lot going for it.
In fact, it’s almost like it’s begging to be turned into a portable game system. Fellow Tindarian Fabien Chouteau had this exact thought, and so the Micro:Gamer was born. This expansion includes a 128×64 monochrome OLED screen, six buttons, a buzzer, and a AAA battery holder.
The micro:bit actually slides into the back of the board like a cartridge from the Game Boy era. Using the Arduino IDE and a library based on the Arduboy, it’s easy to port games from that system to this one, thanks to the identical button layout.
