Skystars F405HD Mini V2 Flight Controller

The Skystars F405HD Mini V2 is a compact 20x20mm flight controller designed for sub-250g freestyle, cinewhoop, and lightweight 3-inch to 4-inch FPV drone builds. Built around a 168MHz STM32F405 processor, it features a direct plug-and-play connector for digital video systems like the DJI O3 Air Unit, Walksnail Avatar, or Caddx Vista, streamlining your wiring layout and reducing bench time.

Key features

• Plug-and-play digital VTX connector eliminates the need to solder your HD video transmitter.
• Six hardware UARTs provide ample routing for GPS modules, serial receivers, and telemetry.
• Integrated 16MB Blackbox flash memory ensures you capture complete flight logs for PID tuning.
• Dual high-output BECs deliver clean power to both standard 5V peripherals and 10V digital video units.
