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 1.6mm thick, with the height and width of a credit card, and was initially designed by Kevin Bates as an electronic business card.
Later consumer versions replaced the first version's touch-sensitive panels by physical buttons, and include a protective plastic case, raising the thickness to 5mm. As well as the open-source Arduboy itself, a single-game version featuring an officially licensed version of Tetris is also available.
Development was funded through a Kickstarter campaign in 2015.
