    What is new on the H743-Wing V2

    1. Use ICM42605 instead of ICM20602
    2. Moved PDB/current sensor from FC board to bottom plate.
    3. Moved 8A BEC from top board to bottom plate.
    4. JST-GH connector for CAN port instead of JST-SH connector.
    5. Add a JST-GH connector for I2C2, for plug and play with ASPD-4525

    ArduPilot

    INAV

    • Current sensor range is 220A on H743-WING-V2,  make sure you set the Current Meter Scale to 150
    • IMU ICM42605 is supported by INAV3.0.2 or higher.
    • MPU6000 is the first IMU(IMU0, default), ICM42605 is the 3rd IMU (IMU2) in INAV MATEKH743 target.
    • If you want to try the new ICM-4 series of IMUs.  download inav_3.0.2_MATEKH743.hex
      • set gyro_to_use = 2
      • set acc_hardware = icm42605
      • save
    • If you stick with MPU6000 only,  H743-WING-V2 works with stable version 3.0.x downloaded from configurator also.
    • Known issue, SD card and MSC mode for H743 is not implemented.

    Others

    • If the ESCs you are using don’t have enough capacitors integrated,  low ESR electrolytic capacitor is required for reducing ESC noise.
