Specifications

  • MCU: STM32H743VIT6, 480MHz, 2MB Flash
  • IMU: BMI088/BMI270
  • Baro: DPS310
  • Compass: IST8310
  • OSD: AT7456E
  • MicroSD Card Slot
  • 7x UART
  • 10x PWM
  • 1x CAN
  • 1x I2C
  • 1x SWD
  • 2x ADC (VBAT, Current)
  • USB Type-C
  • BEC 5V 3A output (for controller, receiver, GPS, optical flow or other devices)
  • BEC 9V 3A output (for video transmitter, camera)
UART Mapping (Ardupilot)
  • SERIAL0 -> USB
  • SERIAL1 -> UART1 (MAVLink2, DMA-enabled)
  • SERIAL2 -> UART2 (VTX-HD, DMA-enabled)
  • SERIAL3 -> UART3 (GPS, DMA-enabled)
  • SERIAL4 -> UART4 (MAVLink2, DMA-enabled)
  • SERIAL5 -> UART6 (RCIN, DMA–enabled)
  • SERIAL6-> UART7 (ESC Telemetry, DMA-enabled)
  • SERIAL7 -> UART8 (DMA–enabled)
UART Mapping (PX4)
  • TEL1 -> UART1
  • TEL2 -> UART2
  • GPS1 -> UART3
  • TEL3-> UART4
  • RC -> UART6
  • ESC -> UART7
  • TEL4 -> UART8
RC Input (Ardupilot)
The default RC input is configured on the UART6. The SBUS pin is inverted and connected to RX6. Non SBUS, single wire serial inputs can be directly tied to RX6 if SBUS pin is left unconnected. RC could be applied instead at a different UART port such as UART2, UART4 or UART8, and set the protocol to receive RC data: SERIALn_PROTOCOL=23 and change SERIAL5 _Protocol to something other than ’23’.
OSD Support  (Ardupilot)
The MicoAir743 supports OSD using OSD_TYPE 1 (MAX7456 driver) and OSD_TYPE 5 (MSP_DISPLAYPORT).
VTX Support
The SH1.0-6P connector supports a DJI Air Unit / HD VTX connection. Protocol defaults to DisplayPort. Pin 1 of the connector is 9v so be careful not to connect this to a peripheral requiring 5v.
PWM Output

The MicoAir743 supports up to 10 PWM outputs.

Channels 1-10 support DShot.

Channels 1-8 support bi-directional DShot.

(currently PX4&INAV not support BDShot function)

PWM output share grouped and every group must use the same output protocol:

1,2,3,4 are group 1

5, 6 are group 2

7,8,9,10 are group 3

Battery Monitoring
The board has a internal voltage sensor and connections on the ESC connector for an external current sensor input.
The voltage sensor can handle up to 6S LiPo batteries.
The default battery parameters(for Ardupilot) are:
  • BATT_VOLT_PIN 10
  • BATT_CURR_PIN 11
  • BATT_VOLT_MULT 21.2
  • BATT_CURR_SCALE 40.2

Compass

The MicoAir743 has a built-in compass sensor (IST8310), and you can also attach an external compass using I2C on the SDA and SCL connector.
