Arduboy FX-C: The Ultimate Pocket-Sized Gaming Companion
The Arduboy FX-C is the latest iteration of the beloved credit card-sized gaming handheld. It crams over 300 pre-installed games into a device thinner than a stack of credit cards, making it the perfect time killer you might forget you're carrying. This open-source gaming device is a major upgrade from its predecessors, offering a massive library and modern connectivity in a truly portable form factor.
What is the Arduboy FX-C?
Originally conceived as a Tetris-playing business card in 2014, the Arduboy has evolved into a commercial device that serves as both a gaming console and a learning tool for aspiring developers. The FX-C model represents over a decade of refinement, combining the minimalist design of the original with powerful new features.
Key Specifications at a Glance
- Processor: ATmega32u4 with 2.5KB RAM
- Display: 1.3-inch monochrome OLED (1-bit)
- Storage: Upgraded flash chip holding 300+ games
- Ports: USB-C (upgraded from microUSB)
- Controls: Six tactile buttons (four form a D-pad)
- Thickness: Just 5mm thin
Design and Hardware: Minimalist but Effective
The FX-C's design is nearly identical to the original Arduboy, but with crucial internal upgrades. The device remains incredibly thin and light, easily slipping into a wallet or coin pocket.
Controls and Feedback
The six buttons have minimal travel due to the 5mm profile, but they offer a satisfying, audible click when pressed. The four-button D-pad is functional for most games, though a traditional cross-shaped pad might be more comfortable for extended play.
Display and Audio
The 1.3-inch OLED screen is bright and readable even outdoors, but it is strictly monochrome. Developers use dithering and flickering to simulate grayscale, a creative limitation that defines the platform's unique charm. The piezoelectric speaker is high-pitched but adequately loud for a device this size.
USB-C Upgrade
One of the most welcome hardware changes is the switch from microUSB to USB-C, eliminating the need for legacy cables without adding any thickness to the device.
Gaming Experience: Over 300 Free Titles
The FX-C's biggest selling point is its massive, pre-loaded game library. With over 300 titles sourced from the Arduboy community, you get incredible variety right out of the box.
Game Library and Variety
Games are organized into categories like Action, Adventure, Arcade, Runner, Puzzle, and Racing. While you won't find commercial classics like Super Mario Bros., you'll discover excellent doppelgängers and original creations that scratch the same itch. The library includes:
- Side-scrollers and platformers
- First-person shooters
- Dungeon crawlers
- Racing games with smooth frame rates
- Puzzle and falling-block games
Pick-Up-and-Play Design
These games are designed for short sessions. The FX-C is perfect for killing a few minutes here and there, not for marathon gaming sessions.
Multiplayer and Future Features
A highly anticipated feature is multiplayer over USB, which uses extra conductors in USB 3.0 or Thunderbolt cables to connect two FX-C units. However, this feature is still in development and was not reliable during testing. If multiplayer is your primary reason for buying, you may want to wait for a software update.
Minor Frustrations
The sliding power switch on the top edge is small and can be difficult to operate, especially for those with short fingernails. Additionally, the menu system lacks an alphabetical listing of all games, which would improve navigation.
Should You Buy the Arduboy FX-C?
The Arduboy FX-C is a fantastic upgrade for fans of the platform and an excellent entry point for newcomers. Priced at $79, it offers incredible value given the hundreds of free games and the thriving developer community. It is not a powerhouse, but its charm lies in its limitations. If you approach it with an open mind, you'll find a uniquely addictive and portable gaming experience.
Pros: Ultra-portable design, huge free game library, USB-C, open-source community.
Cons: Monochrome display, limited controls, multiplayer feature not fully ready.
