Arduboy

The Arduboy is a handheld game console with open source software, based on the Arduino hardware platform. The original version of the Arduboy was 1.6 millimetres (0.063 in) thick, with the height and width of a credit card, and was initially designed by Kevin Bates as an electronic business card. In preparation for a consumer version, the developer moved to Shenzhen, China to work on the Arduboy at the HAX accelerator. Later consumer versions replaced the first version's touch-sensitive panels by physical buttons, and include a protective plastic case, raising the thickness to 5 millimetres (0.20 in). A non-production smaller formfactor "Arduboy Mini" was demonstrated in 2019. Another non-production system, the "Arduboy Nano" was demonstrated in 2021 with an smaller formfactor than the Arduboy Mini.
