The Thumby is a small keychain sized programmable game console produced by TinyCircuits of Akron, Ohio[3][4] and funded by a Kickstarter campaign.[5][6][7] The console measures 1.2 by 0.7 by 0.3 inches (30.5 mm × 17.8 mm × 7.6 mm).


The first concept for the Thumby originated roughly around 2015 or 2016.[3] An early version of the system was shown at the 2016 Bay Area Maker Faire.[8]

A Kickstarter crowdfunding campaign to raise money for the console began on September 28th, 2021.[9][10] The company projected a production of at least 10,000 Thumby consoles despite the 2020–present global chip shortage.[3] A stated goal was to ship consoles to backers by February 2022, with plans to ship some early units in Fall 2021.[3] The console shipped in 2022.[11]


The Thumby includes six preloaded games:

Additional games can be downloaded from the internet on a personal computer, then loaded onto the console over USB.


The Thumby is powered by a Raspberry Pi RP2040 microcontroller.[7] The console provides 2MB of onboard storage.[7] MicroPython is supported with a web based development environment.[12]

A small 0.38 by 0.27 inches (9.7 mm × 6.9 mm) 72x40 pixel 1-bit OLED panel is used as the display.[13][7][14] A buzzer is also included[15] for simple audio feedback.

A microUSB port is used to connect the console with computers, as well as to support the Thumby link cable.[7] This port is also used to charge the lithium polymer battery, which provides about 2 hours of operational runtime with a capacity of 40mAh.[7]

The system is notable for its small size, measuring at 1.2 by 0.7 by 0.3 inches (30.5 mm × 17.8 mm × 7.6 mm).[13] The console can be mounted on a keychain.[10][13] The system has a mass of 4.7 grams (0.17 oz).[16]

The console casing was made in a variety of colors including gray, blue, and pink.[17]
