Board - BeeRotor F4

BeeRotor F4 front

BeeRotor F4 back

Features

  • STM32F405 CPU
  • Integrated Accelerometer/Gyro MPU6050 via SPI bus
  • Barometer BMP280
  • 8 motor outputs
  • 3 UART ports (UART1, UART2, UART3)
  • External SPI bus
  • UART2 and UART3 are equipped with inverter
  • SD Card slot for logging
  • LED connector
  • Buzzer connector
  • Integrated OSD

Currently NOT supported

  • inverter on UART3
  • IR transmitter output

Radio Receivers

SerialRX, PPM and MSP receivers are supported.

SerialRX and PPM receivers should be connected to dedicated PPM SBUS pin on the RX connector. MSP receivers should be connected to one of UARTs configured as MSP.

USB

This board uses STM32 VCP and not utilizes UART when USB is connected. STM32 VCP drivers might be required!

Flashing requires DFU mode and STM32 DFU drivers. Use Zadig tool to install WinUSB driver on Windows.

Buzzer / Beeper

5V piezo buzzer should be connected directly to dedicated pins BUZ + and BUZ -. No additional hardware is required.

RSSI monitoring

  • Use the dedicated RSSI pin on the RX connector.
  • 3.3V tolerant, do not supply 5V

Current monitoring

  • Use the dedicated SI pin on the PDB connector, or the SI pad on the board.
  • 3.3V tolerant, do not supply 5V

Voltage monitoring

  • Use the dedicated SI pin on the PDB connector, or the SV pad on the board.
  • 3.3V tolerant, do not supply 5V
  • SV pin on the PDB connector does not have a voltage divider. It requires a voltage divider on the PDB, or the board will be destroyed! (The SV pad on the board has a voltage divider, use this if your board doesn't.)

LED Strip

  • Use the dedicated LED pin on the LED / buzzer connector.
