Tips And Notes:

*** V1/V2/V3 share same ArduPilot/INAV Target ***

ArduPilot

  • Current sensor range is 220A on H743-WING-V2/V3,  make sure you set the BATT_AMP_PERVLT to 66.7
  • with ArduPilot 4.1 or higher, set INS_ENABLE_MASK to 7 or default 127.
  • Pls download “plane 4.2.0 or newer” ArduPilot firmware for H743-WING-V3
  • It is recommended to use STM32CubeProgrammer to erase MCU and upload firmware.  check this blog http://www.mateksys.com/?p=6905

INAV

  • Current sensor range is 220A on H743-WING-V2/V3,  make sure you set the Current Meter Scale to 150
  • H743-WING-V3 is not supported by INAV4.1 downloaded from configurator. pls download inav_4.1.0_MATEKH743_42688 from our website.
  • Starting with INAV5.0, they will share the same firmware.

Others

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