TinyCircuits Thumby is a gaming handheld launched in 2022. Powered by RP2040 (2-core, 133 MHz), 264 KB RAM. Features a 0.42" OLED display (72 x 40). 40 mAh battery. Runs Custom Firmware.

The TinyCircuits Thumby is a micro vertical handheld launched in 2022 and one of the smallest gaming consoles around. Its plastic body measures just 18 x 29.5 x 8.5 mm and weighs 4.7 g. Thumby is not an emulation device: it plays its 5 included games plus homebrew titles made specifically for the platform.

Inside is the Raspberry Pi RP2040 chip, with two Cortex-M0+ cores (ARM architecture) running at 133 MHz, paired with 264 KB of SRAM and 2 MB of NOR Flash storage. These resources are modest, but they are well suited to simple games designed around this hardware, which run smoothly on the tiny screen.

The display is a 0.42-inch monochrome OLED with a 72 x 40 resolution, 9:5 aspect ratio, roughly 196 ppi and a 60 Hz refresh rate. The contrast typical of OLED keeps simple graphics crisp, and the panel is covered only by a protector rather than a lens.

Controls are kept to the essentials: a cross-shaped D-pad in the lower position and two face buttons. There are no analog sticks, no shoulder buttons and no rumble. Power is handled by a switch, volume is adjusted through the menu, and audio comes from a single rear-facing mono speaker.

Power comes from a 40 mAh battery charged over Micro USB, suited to short play sessions.

Thumby runs a proprietary operating system, and its real strength is programmability: homebrew games can be built with MicroPython or the Arduino IDE. That makes it an excellent platform for learning to code and creating your own games, at a reference price of just 19 USD.

Ideal for: fans of miniature gadgets, beginners who want to learn programming through games, homebrew developers working in MicroPython or the Arduino IDE, and anyone looking for an original, affordable gift.
