Description
The RadioLink F405 Flight Controller is an all-in-one flight control system that integrates high performance, exceptional reliability,
and intelligent design, tailored for multi-scenario applications such as racing drones, aircraft, and multi-rotor UAVs.Combining a decade of RadioLink’s independent flight control R&D expertise with industrial-grade hardware design philosophy,
the F405 delivers unparalleled control experience and enhanced flight safety. Redevelopment is supported: https://github.com/betaflight/config/tree/master/configs/RADIOLINKF405
https://github.com/ArduPilot/ardupilot

Supports Multiple Open-source Firmware
F405, fully compatible with mainstream open-source firmware of ArduPilot, Betaflight, and INAV, achieves razor-sharp responsiveness for racing scenarios and robust stability for autonomous flight.

High-End Configuration
Equipped with the STM32F405RGT6 main control chip, delivering powerful computing capabilities and ultra-fast processing speed, 168MHz core frequency; features an ICM42688 high-precision gyroscope with dedicated LDO power supply for lower noise and faster response; dual gyroscope pads reserved for optional MPU6500 replacement to meet diverse needs; paired with the SPL06-001 high-precision barometer for enhanced accuracy in altitude hold and return-to-home operations.

Storage Capacity
128MB high-capacity blackbox, enabling comprehensive flight data recording and supporting long-term fault tracing.

Power Supply Optimization
4.5V/5V isolated circuit design* prevents device damage from current overload during parameter adjustments;
9V programmable BEC switch enables flexible video transmission power control*.
