Arduboy

Arduboy is an 8-bit mini gameboy that is the size of a credit card. It provides a convenient and educational platform for kids to learn programming based on Arduino and for all to enjoy classic games or to create new ones. 

This coding game has a clear polycarbonate front and silver metal back to illustrate simplicity. A true balance between thickness, durability, practicality, and cost - it is only 5mm thick and can fit in your wallet!
