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.
If you prefer to use a separate ESC for each motor, the companion product, the RADIX 2 Power Board (PB) got you covered. It is designed for serious power and can handle up to 8S (35 V) battery voltage and 160 A constant current (220 A burst). It also features an LC filter and voltage regulator for clean power to the flight controller and connected peripherals.
