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 (non-open) version of Tetris is also available. Development was funded through a Kickstarter campaign in 2015.
