BrainFPV Radix, the smartest, most innovative line of drone electronics BrainFPV has ever developed.
BrainFPV brings us their latest creation, the Radix Flight Controller. With a speedy F4 processor, full graphics capable OSD, and stackable form factor, this FC has all the essentials but with many things, it's the details that count. There are so many, you'd be better off looking at the specs yourself.
  • Best setup manual ever made
  • Improved form factor for easier soldering of PDB / 4-in-1 ESC underneath RADIX FC
  • Plug-and-play stacking on RADIX PB or Hobbywing 4-in-1 ESC using soft cables for vibration isolation
  • Graphical OSD - the only flight controller running BF with this feature
  • Customisable OSD logos using the BrainFPV Logo Customiser
  • STM32 F4 processor running at 180MHz
  • Better sensors - Bosch BMI160 gyro, proven on RE1 (pilots are raving about it)
  • Integrated barometer - so you always know how high you are 
  • MicroSD card slot for logging
  • Integrated silicone grommets for vibration isolation
  • Dedicated camera control pad for changing camera settings
  • Dedicated RGB LED output for programmable LEDs
  • Four full hardware serial ports (UARTs) - two of them have signal inverters that are automatically enabled or disabled, so they can be used with S.Bus or SmartPort
  • 6 motor outputs with support for DHSOT (150/300/600/1200) and OneShot
  • Supports Betaflight
  • Engineered and tested in the USA


  • Processor: STM32F446RET6, Coretx-M4, 32bit, 180MHz, 128kB RAM, 512kB Flash.

  • IMU: Bosch Sensortec BMI160 running at 3.2kHz, connected using SPI.

  • Baro: Bosch Sensortec BMP280 connected using SPI.

  • OSD: Full-graphic, PAL/NTSC auto detect, adjustable black and white levels. Full Betaflight OSD support with extra graphical features.

  • BEC: 5V, 2A with Radix PDB

  • Memory: MicroSD card slot for logging.

  • Motor Outputs: 6 outputs with full DSHOT (150/300/600/1200) and OneShot support.

  • Receiver Support: PPM, S.Bus (inverter built-in), DSM, HoTT, SRXL, CSRF, F.Port ready. 5V or 3.3V supply for a receiver.

  • Telemetry Support: FrSKY Smart Port, FrSKY Sensor Hub, HoTT Telemetry, SRXL, CSRF, F.Port ready. Built-in inverter for FrSKY telemetry.

  • Serial Ports: 4 full serial ports (UARTs). UART3 and UART6 have inverters for S.Bus and SmartPort telemetry. 

  • RGB LEDs: Dedicated RGB LED output.

  • Camera Control: Dedicated output for accessing the camera menu to change camera settings.

  • IR Emitter: Dedicated output for infrared-based lap timing with multi-protocol support (I-Lap, Trackmate). Needs external IR LED and driver.

  • Buzzer Port: Dedicated port for 5V (100mA max) buzzers.

  • Analog Inputs: Voltage sensing up to 35V, current and RSSI inputs (3.3V max).

  • Power: 4.5V to 5.5V, 120mA.

  • Dimensions: 37mm x 37mm, 30.5mm hole spacing. 4.1mm holes for anti-vibration grommets.
