Thumby Keychain Game Console
Thumby is unofficially the world’s smallest Game Boy-like keychain console, built around the Raspberry Pi RP2040 processor. Despite its size, it boasts fully functional electronics, such as a buzzer, battery, power switch, gameplay buttons, micro USB, and a 72×40 OLED monochrome screen.

Yes, it even comes preloaded with a total of five retro games, but users can easily add more. That’s not all, experienced programmers have the ability to recreate their favorite ‘90s games. At just 1.2″ x 0.7″ x 0.3″, Thumby fits on just about any keychain or pocket. It is available in a classic grey with a black directional pad and red A/B buttons for $19 USD.

We’re all makers here and we’re able to make projects that don’t exist, but we wish would exist in reality. Thumby came from our nostalgia for ‘90s retro games (we have a collection of game cartridges and an arcade in the back). Wouldn’t it be cool to have a well-crafted, meticulously made small keychain that is actually playable and programmable? And we can make that happen because we specialize in tiny circuits and design and manufacture in house,” said Ken Burns, President of TinyCircuits.
