Arduboy projects and devices

Arduboy is represented by the FX-C, a credit-card-sized ATmega32U4 handheld with a monochrome OLED, physical controls, audio, and flash storage for homebrew games. Flashable connects it to the Arduboy2 Arduino library, whose examples and APIs cover drawing, sprites, buttons, sound, collision helpers, and frame timing. This is a constrained 8-bit game-development target rather than a general display board: program and RAM budgets reward smaller library variants and selective features. Arduboy2 coexists with the older Arduboy library under a different class name, and saved data must stay above the library’s reserved EEPROM system area.
