The Pandora is a handheld gaming computer originally released in 2010. It is designed to take advantage of existing free and open-source software and to be a target for homebrew development. It is developed and produced by OpenPandora, which is made up of former distributors and community members of the GP32 and GP2X handhelds. Until 2013, multiple batches of slightly updated Pandora variants were produced. In 2014 the development of a redesigned and upgraded successor, called DragonBox Pyra, was started.

A handheld personal computer (PC), typically built around either a clamshell form factor or a gaming form factor with a gamepad integrated for video games, is a mobile device that is significantly smaller than any standard personal computer (PC), but based on the same principles as PCs. The clamshell form factor is sometimes referred to as a palmtop computer, not to be confused with Palmtop PC which was a name used mainly by Hewlett-Packard.
