Thumby Keychain Game System
Developed by TinyCircuits, the Thumby is basically the world’s smallest Game Boy. It measures just 1.2″ x 0.7″ x 0.3″, and packs a Raspberry Pi RP2040 processor and a tiny 72×40 OLED screen. The system comes pre-loaded with five retro games, and players can upload their own custom games. Launches on Kickstarter 9.28.2021 for $19.
