Thumby: The World's Smallest Handheld Gaming Device

Thumby by TinyCircuits is a tiny, keychain-sized retro gaming handheld with a 0.42-inch monochrome OLED display, powered by a Raspberry Pi RP2040 chip. It supports homebrew games via MicroPython or Arduino IDE.

Overview

The Thumby is a remarkably small handheld gaming console developed by TinyCircuits. Measuring just 18 mm x 29.5 mm x 8.5 mm and weighing only 4.7 grams, it can easily attach to a keychain. Despite its size, it packs a Raspberry Pi RP2040 microcontroller with a dual-core Cortex-M0+ CPU running at 133 MHz, 264 KB of SRAM, and 2 MB of built-in storage. The device features a 0.42-inch monochrome OLED display with a resolution of 72x40 pixels and a 9:5 aspect ratio. It comes preloaded with five built-in games and supports homebrew development using MicroPython or the Arduino IDE.
