RADIX 2 Flight Controller

The BrainFPV RADIX 2 flight controller is one of the most feature-packed and highest performing flight controllers on the market. It is the successor of the legendary BrainFPV RADIX flight controller where pretty much everything has been vastly improved. From a blazing fast H7 processor running at 480 MHz, an improved graphical OSD, to 8 motor outputs, driverless flashing, and more.

Description

BrainFPV RADIX 2 Technical Specifications

• 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.
• 32 MByte built-in flash memory:30 MByte available for logging and settings storage
• Driverless flashingwith the BrainFPV USB mass storage bootloader. Simply copy the firmware file to the flight controller when connected to your computer. No more messing with DFU drivers
• RGB status LEDwith customizable color
• 8 motor outputs:all supporting bi-directional DSHOT for RPM filtering. All outputs are available on connectors for easy connection of one or two 4-in-1 motor controllers (ESCs).
• 6 serial ports (UARTs):all with integrated inverters for S-BUS and other inverted protocols
• I2C portfor external sensors
• RGB LED output
• Buzzer output
• Camera controloutput for configuring analog cameras
• Analog RSSI input
• 5 V regulatorwith 1.5 A output and up to 8S (35 V) input voltage
• USB Type-C connector
• Size: 37 x 37 mm (30.5 mm hole spacing)
• Weight: 7g

Changes for RADIX 2 Revision 2.0 Released in 2024:

• Improved barometer: Infineon DPS310
• Improved 5 V voltage regulator that we also use in the RADIX 2 HD

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!

You can use 24-in-1 ESCs for an octocopter. Holy mother of FPV! It comes with cables and connectors to easily make your own wiring harness.
