ATOMRC F405 NAVI Flight Controller STM32F405 BMI270 SPL06 Baro OSD SD Blackbox Type-C 5V/9V BEC INAV ArduPilot

Overview

The ATOMRC F405 NAVI Flight Controller is a fixed-wing Flight Controller designed for INAV and ArduPilot setups, with integrated OSD, barometer, current sensing, and Micro SD blackbox support. It includes an external Type-C adapter/buzzer board for convenient access when installed in an airframe.

Key Features

• Supports INAV and ArduPilot firmware targets: ATOMRCF405NAVI (INAV 5.0 or newer stated)
• Integrated barometer and current sensing (ammeter)
• Micro SD card slot for blackbox logging
• OSD: AT7456E
• External USB Type-C adapter board (BOOT/Type-C) with buzzer support
• 8 PWM outputs
• VTX power output selectable 5V/9V (9V/5V VTX voltage bridge shown)
• LED support: WS2812S serial LED
• SBUS inverter on UART2-RX (note: Rx2 and SBUS cannot be used at the same time)
• Vibration-isolation mounting concept using silicone ring (feature text provided)
• Plug-and-play wiring shown for DJI Air Unit and BN-180/BN-220 GPS modules

Details

Designed for fixed-wing navigation builds, the F405 NAVI integrates OSD, barometer, current sensing, and Micro SD blackbox logging.

An external TypeC adapter/boot board makes USB access and setup easier once the controller is installed in the airframe.

Silicone-ring mounting helps reduce high-frequency vibration for cleaner gyro performance in fixed-wing installations.

The 5030 mm footprint and low stack height fit many common fixed-wing bays and mounting patterns.

Key hardware highlights include an STM32F405 MCU, BMI270 IMU, SPL06 barometer, AT7456E OSD, and 5V/9V power outputs.

Port and pinout guidance covers GPS, DJI Air Unit, VTX control, camera, WS2812 LED support, and power connections.
