** H743 Flight controller, with dual IMU and compass sensor built-in, supports Ardupilot/PX4/INAV/Betaflight.**
Ardupilot
MicoAir H743 flight controller is officially supported by Ardupilot starting from version 4.6. You can update the firmware through Mission Planner or download all the firmware files (Copter/Heli/Plane/Rover/etc) here:

You can also use the online firmware builder provided by Ardupilot to customize your firmware for MicoAir743:

Old version (v4.5.1) firmware can be downloaded here:

PX4
MicoAir743 flight controller is officially supported by PX4 from version 1.15.0.
You can also download the firmware and bootloader built by us (1.13.3 & 1.14.0):

Betaflight
MicoAir743 flight controller is officially supported by Betaflight from version 4.5.0.
INAV
MicoAir743 is officially supported by INAV from version 8.0.0. You can also download the old version firmware built by us:

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 the 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 do 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 an 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.
