GAN251 UI 2×2 – smart tracking in a pocket 2×2
The 251 UI is GAN’s 2×2 smart cube built around a compact 21 mm core and non-contact Hall sensors, so every turn is recorded without adding friction to the mechanism. It rests on the included wireless charging base — a short charge gives around 30 hours of use — and sends timing, move count and turn-by-turn data to the CubeStation app.
UV Coated – light, fast and always ready
- 21 mm 2×2-exclusive core with omnidirectional core positioning
- Zero-loss Hall sensing: tracks every rotation with no missed turns
- 72 hand-feel combinations for tension, magnet feel and travel
- Wireless charging base, up to 30 h battery life
Who it’s for: 2×2 solvers who want app-based solve analysis without carrying a separate timer, and anyone putting together a connected GAN smart setup.
The nutshell
One version, one job: the smallest way to get every 2×2 solve into CubeStation. For the flagship 3×3 smart cube, see the GAN16 ui Maglev MAX.
