PRODUCT INFORMATION

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.

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.

Changes for RADIX 2 Revision 1.2 Released in 2022:

  • Improved barometer: Omron 2SMPB-02B
  • TVS diode (“spike protector”) to protect 5 V regulator from voltage spikes
  • Removed VTX pit switch over-current protection. Pit switch can supply up to 1.5 A
  • Made in Oregon, USA!
