HGLRC Specter F722 Mini 2–6S 20×20 Flight Controller

The HGLRC Specter F722 Mini is a 20x20mm flight controller built for compact 2–6S freestyle, racing, and cinewhoop drones. Powered by an STM32F722 processor, it delivers fast loop times and reliable computing power for demanding flight dynamics in tight 3-inch up to lightweight 5-inch frames.

Key features

• Direct plug-and-play connector for digital HD video systems (DJI O3, Walksnail, Caddx Vista) to reduce wiring and soldering.
• Dedicated 5V and 10V BECs to cleanly power receivers, GPS modules, and high-draw video transmitters.
• Integrated 16MB Blackbox flash memory for PID tuning and comprehensive flight data logging.
• Large, accessible solder pads designed to simplify wiring in tight chassis constraints.
