Arduboy FX-C: credit-card-thin retro handheld with a growing game library

The Arduboy FX-C is a 5mm-thin handheld with six buttons, a 1.3-inch monochrome OLED screen, and USB‑C, preloaded with 300+ games drawn from the Arduboy community. It emphasizes quick, pick‑up‑and‑play sessions over long campaigns and, while its library and pocketable design are strong draws, it lacks a color screen, Wi‑Fi/Bluetooth, and expandable storage. USB multiplayer is still in development, so some buyers may want to wait for that feature to mature.
