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.
