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.
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.
