Radiolink F405 Ardupilot Betaflight INAV Flight Controller 6 Channels 4-in-1 ESC Stack SBUS/CRSF FC for Racing Drone, Quadcopter

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.

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 a BMI270 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.

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*. *Integrated multi-channel BEC: 3.3V/300mA, 5V/3A, and 9V/3A outputs support external peripherals including receivers, FPV transmitters, cameras, servos, LED strips, and other types of devices. *Video transmission power management: video transmission power can be toggled directly via remote controller, or parameters like transmission power and frequency can be adjusted through remote-FPV goggle synergy.

2oz thickened copper PCB technology enhances current capacity by 50% and reduces electromagnetic interference (EMI). Extensive capacitor filtering ensures cleaner circuit signals and more stable chip operation. Triple-layer protection with ferrite beads, TVS diodes, and high-voltage-tolerant DC chips effectively suppresses motor back-EMF surges, minimizing flight control board burnout risks.

Within a compact 30.5×30.5mm footprint, the F405 supports 6 output channels and is compatible with a wide range of models, including 2-6-axis multi-rotors, fixed-wing aircraft, helicopters, flying wings, cars, boats, robots, lawn mowers, and bait boats.

All-in-One Plug-and-Play Interfaces It supports a direct 6-pin connection to the DJI O3/O4 plug-and-play and seamless compatibility with peripherals such as GPS, OSD, and video transmitters, delivering unparalleled expandability.

Parameters can be adjusted via Radiolink and open-source Mission Planner, Betaflight, and INAV Configurator while monitoring critical parameters such as voltage and attitude in real time through the OSD interface.

Kontroler wyposażono w optymalne rozmieszczenie padów i gniazd, zgodne z popularnymi ramami modeli, co zwiększa wydajność lutowania i prowadzenia kabli o 40%.

Seamlessly supports bidirectional DShot digital throttle communication, DShot, OneShot, and PWM signals while also enabling ESC telemetry feedback.

Supports SPEKTRUM, SBUS, TBS Crossfire(Black Sheep), and ExpressLRS receiver, ensuring full compatibility with all mainstream remote controllers on the market.

Unique Automation Software Testing System Featuring a self-developed, industry-leading full-parameter testing process, every flight control unit undergoes 20 rigorous tests, including high-temperature resistance, vibration tolerance, signal stability, and port functionality verification. This system not only ensures high production efficiency but also guarantees comprehensive full-parameter and full-functionality testing for each flight control board.
