Arduboy FX-C shrinks retro gaming into a pocket-sized handheld
Arduboy’s FX-C packs 300-plus games, multiplayer support and USB-C into a shell thinner than stacked credit cards. It is a tiny answer to gaming hardware that keeps getting bigger.

Arduboy’s FX-C lands as a deliberate counterpoint to the handheld market’s bigger screens and heavier batteries. The device is no larger or thicker than a few credit cards stacked together, yet it adds USB-C, keeps the external flash memory from the earlier Arduboy FX, and can hold more than 300 games on board without requiring players to reflash between titles.
The company introduced the FX-C in November 2025 and framed it as more than a cosmetic refresh. Arduboy says the handheld now supports multiplayer and link-cable play, and its quick-start materials include a sample of multiplayer games. A separate multiplayer pack was offered to highlight the two-player setup, a sign that the platform is trying to widen its appeal beyond solitary collectors and into shared play.
That strategy builds on a platform with a long tail. Kevin Bates launched Arduboy on Kickstarter more than 10 years ago, and the original device shipped to backers in August 2016. Since then, Arduboy has kept the concept alive with the Arduboy FX memory upgrade and the Arduboy Mini, a smaller version meant to broaden access while preserving compatibility with the same game library.
The FX-C’s selling point is not raw power. It is the combination of pocketability, simplicity and convenience, wrapped in Arduino-based 8-bit gaming hardware that still has a clear place in STEM-friendly classrooms and among tinkerers. In a market where portable gaming often chases bigger displays and console-like performance, Arduboy is betting that a deliberately tiny machine can stand out by doing less, better.

That niche remains visible in the product’s rollout. Arduboy says the FX-C is available through its shop, Amazon and distribution partners, and at one point the shop page showed only 153 units available. The founders edition, with purple buttons and a serialized limited production batch, further signals that this is a device for collectors as much as players. For the wider gaming market, the FX-C may read as a novelty. For Arduboy’s audience, it is a compact proof that retro hardware can still feel current.
