dotMG: Arduboy-compatible, Cartridge-Based DIY Game Console

Designed to remind you of the early days of handheld gaming, dotMG combines game cartridges with Arduboy greatness!

This project was designed with fully customized PCBs and is completely open-source. It features:

• Swappable game cartridges based on the Arduino Pro Micro (including reverse cart protection)
• Hackability via EXT header (exposes SPI/I2C/GPIO pins) -- add your own crank, accelerometer, joystick, flash chip, RGB LED, or any other add-on of your own creation!
• Rechargeable battery (with play 'n charge capability via load-sharing circuitry)
• Analog volume control
• Large 2.44" 128x64 OLED display

This project is completely open-source! All instructions and materials can be found at: github.com/menehune23/arduboy-dotmg
