The RADIX 2 is the latest generation flight controller by BrainFPV. It is the successor of the legendary RADIX flight controller and everything has been vastly improved. From a blazing fast H7 processor running at 480 MHz, an improved graphical OSD, a built-in voltage regulator that can handle up to 8S (35 V), to 8 motor outputs, driverless flashing, and more.

BrainFPV is famous for bringing the BEST documentation and a unique Bosch gyro. The Radix 2 is now using a NEW Bosch Sensortec BMI270 Gyro. They have also upgraded to a NEW Bosch Sensortec BMP388 barometer.

BrainFPV is also known for the first Graphical OSD system with custom pilot logos and start screens and this has been improved even more with Radix 2.

The RADIX 2 is designed to be compatible with any 4-in-1 motor controller (ESC) on the market. For octocopters, you can use the included 5-pin cable to connect a second 4-in-1 ESC for motors 5 to 8. All outputs fully support bi-directional DSHOT that enables the motor controllers to send back real-time telemetry that is used by the flight controller to perform adaptive RPM based noise filtering.

New Processor: STM32 H7 processor running at 480 MHz with 1 MB RAM
New Gyro: New Bosch Sensortec BMI270 gyro / accelerometer delivering superior flight performance
New Baro: Latest generation Infineon DPS310 barometer for accurate altitude readings. Previous revisions used Bosch Sensortec BMP388 (Rev 1.0) or Omron 2SMPB-02B (Rev 1.2)
Better OSD: Improved full graphical on-screen-display (OSD) with gray levels and transparency
Dual camera input: Camera can be switched using a switch on the RC transmitter
VTX pit switch: to turn on/off the video transmitter. Voltage for VTX can be 5 V or the battery voltage.
Note: The original RADIX 2 had over-current protection for the pit switch, which was removed in hardware revision 1.2 released in 2022.
