Supports Multiple Open-source Firmware
The 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*.
- *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.
Anti-Interference Capability
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.
Compact Design, Versatile Compatibility
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.
Intelligent Tuning Support
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.
Installation-Friendly Design
Featuring optimized pad and socket layouts compatible with mainstream frame installations, with soldering and cable routing efficiency improved by 40%.
Supports Mainstream Throttle Signals
Seamlessly supports bidirectional DShot digital throttle communication, DShot, OneShot, and PWM signals while also enabling ESC telemetry feedback.
Supports Multiple Signal Protocols
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.
Cost-effective Solution
The F405 Flight controller works with the 16 channels remote control system T16D, the 16 channels receiver R16F, the 50 Centimeters Positioning Accuracy GPS TS100, the DJI/CADDX high-definition digital image transmission, and HD Goggles, and the ELRS long-range module, almost all the parts of the RC drone you need we can offer, realizing the super adaptability of various cost-effective solutions such as high-speed aerial photography and cinematography solutions.
