Description

** 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: ArduPilot Firmware Download You can also use the online firmware builder provided by Ardupilot to customize your firmware for MicoAir743: ArduPilot Custom Firmware Builder Old version (v4.5.1) firmware can be downloaded here: MicoAir743/Firmware/Ardupilot(v4.5.1) User Manuals and Tutorials (updated in real-time) MicoAir H743 Manuals & Tutorials 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): MicoAir743 PX4 Firmware 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: MicoAir743 INAV Firmware Specifications (FC) 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 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.

More features

Wide Compatibility: Supports all major open-source flight control systems, including Ardupilot, PX4, and Betaflight, with official firmware support. INAV will be officially supported from version 8.0, ensuring your flight control system stays up-to-date with the latest technology.
High-Precision Dual IMU Sensors: Equipped with dual IMU and an integrated compass, providing higher-quality IMU data for navigation tasks such as waypoint flying or hovering, significantly improving the accuracy of navigation and positioning in complex environments.
DJI O3 FPV Support: Specifically designed compatibility with the DJI O3 Air Unit, supporting HD video transmission and providing a smooth first-person view (FPV) flying experience, meeting professional-grade FPV demands.
Rich Expansion Interfaces: Features 7 UARTs, 10 PWM outputs, USB Type-C, and support for CAN and I2C buses, allowing connectivity to a variety of external devices such as onboard computers and optical flow laser sensors, offering extensive expandability.
High-Performance MOSFET Devices ESC: The Electronic Speed Controller uses 40V 165A RDS=1.1mR MOSFET devices, which are key to enhancing ESC performance. An RDS(ON) as low as 1.1mR means minimal internal resistance during current flow, reducing energy loss, increasing efficiency, and resulting in lower heat generation and better load capacity. Especially during long periods of high load, this significantly lowers failure rates and extends lifespan.
User-Friendly Design and Support: Features an all-connector design to reduce soldering work and improve connection reliability. Additionally, we offer detailed usage tutorials and continuously update settings and optimization guides for different firmware, helping users get started with ease.
