Product Details
BrainFPV's RADIX 2 HD is an evolution of the legendary RADIX 2 flight controller, designed to be used with HD (Digitial) FPV Systems.
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.
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.

Features:
- Powerful processor: STM32H750 processor running at 480 MHz with 1 MB RAM
- Superior gyro: Bosch Sensortec BMI270 gyro / accelerometer delivering superior flight performance you are used to from the RADIX 2
- Accurate barometer: Infineon DPS310 providing accurate altitude information
- Designed for HD FPV: Compatible with all digital HD FPV systems currently available, plug-and-play connector for DJI HD FPV system
- 8S compatible: Can be powered directly from up to 8S (35 V) battery voltage
- 12S voltage sensing: When used with more than 8S, it can still measure the battery voltage, but needs to be powered using a lower voltage (e.g. 12 V)
- 16 MB built-in flash memory: For firmware, flight logs, and settings storage
- Micro SD card slot: Provides even more space for storing flight logs
- BrainFPV bootloader for driverless flashing: Simply copy the firmware file to the flight controller when connected to your computer. No more messing with DFU drivers. Can also be used for downloading logs from the Micro SD card
- 8 motor outputs: All outputs are available on connectors for single or dual 4-in-1 ESC connection. Bi-directional DSHOT for RPM filtering is supported on all outputs
- 2 servo outputs: In addition to the 8 motor outputs, the UART6 pads can be configured to be servo outputs
- 6 ½ serial ports (UARTs): 6 full ports and one RX-only port for HD system RC control connection. All with integrated inverters for S-BUS and other inverted protocols
- I2C port for external sensors
- CAN bus port for future extensibility (not currently supported in Betaflight and INAV)
- RGB status LED with customizable colour
- RGB LED output
- Buzzer output
- Analog current sensor input
- Analog RSSI input
- 5 V / 1.5 A regulator for powering the RADIX 2 HD itself and other 5 V devices (RC receiver, GPS, etc.)
- 9 V / 2.0 A regulator with pit switch for HD system: The pit switch allows you to turn off the HD system to keep it cool before take off
- Spike protector (TVS diode) to prevent damage from voltage spikes
- USB Type-C connector
- Size: 37 x 37 mm (30.5 mm hole spacing)
- Weight: 7g
- Supported firmware: Betaflight, INAV
- Made in the USA - NDAA compliant
The Differences: Radix 2 HD vs. Radix 2
BrainFPV’s Radix 2 hd and Radix 2 share a lot of similarities. For example, they both use the same blazing fast h7 processor and bmi270 gyro, and both include a plug-and-play connector for dual 4-in-1 esc’s. Both fc’s deliver unparalleled flight performance. here are the differences between the two:
- Designed to be used with hd systems: No analog osd
- Improved voltage regulators and filtering
- Micro sd card slot
- Can bus port
- Plug-and-play connector for HD systems
I2C port for external sensors
Package Includes:
- 1 x RADIX 2 HD flight controller
- 4 x Silicone anti-vibration grommets
- 1 x BrainFPV 4-in-1 ESC cable kit (cables and connectors to make a cable that works with any 4-in-1 ESC with a JST-SH 7 pin, 8 pin, or 10 pin connector)
- 1 x 5-pin cable for motor outputs 5 to 8
- 1 x 6-pin cable for custom HD system connection (for DJI, the cable included with the Air Unit can be directly connected to the RADIX 2 HD)
- 1 x Stickers
