Radiolink F405 Flight Control Board

Radiolink F405 Autonomous Flight Controller

The Radiolink F405 Autonomous Flight Controller is a next-generation, high-performance autopilot system engineered for FPV racing drones, autonomous UAVs, fixed-wing aircraft, and robotic automation platforms. Powered by its robust **32-bit STM32F405RGT6** main control chip running at a core frequency of 168 MHz, it processes complex flight calculations and multi-sensor commands flawlessly in fractions of a millisecond.

Its high-end configuration integrates a high-precision IMU sensor suite alongside an **SPL06 barometer**, providing razor-sharp stabilization and precise altitude hold capabilities even under harsh, windy flight environments. Featuring an onboard **AT7456E OSD chip** and a massive **128 MB Blackbox** memory capacity, it overlays vital telemetry directly onto your video feed and stores comprehensive flight logs for easy diagnostic tracing. It delivers native, hardware-level optimization for world-leading open-source flight stacks including ArduPilot, Betaflight, and INAV.

Key Features:

• Multi-Channel Isolated BEC Suite: Integrated 3-channel BEC (3.3V/300mA, 5V/3A, and a programmable switch-enabled 9V/3A) cleanly powers receivers, cameras, servos, and high-wattage VTX systems without an external PDB.
• Plug-and-Play Video Connectivity: Offers direct dedicated socket connections for both modern DJI O3/O4 HD digital air units and traditional analog video transmitters (VTX).
• Industrial-Grade Circuit Protection: Engineered with TVS protection diodes, thickened copper PCB layers, and heavy capacitor filtering to shield the board from voltage spikes and EMI noise.
• Rich Hardware Expansion (5x UARTs): Features 5 physical hardware UART ports plus an I2C bus to effortlessly interface with external GPS modules, compasses, RTK kits, and telemetry systems.

Technical Specifications:

Application Areas:

• High-speed FPV racing quads, freestyle multirotors, and industrial commercial drone configurations (2 to 6 axes).
