Tips

H743-WLITE vs F765-WSE

• STM32H743VIH6  vs STM32F765VIH6
• RX4/TX4 vs RX5
• Other components and layout are identical.

ArduPilot

• 220A Current sensor on H743-WLITE, , BATT_AMP_PERVLT to 66.7
• 1k:20k voltage divider for battery voltage sense on H743-WLITE,  BATT_VOLT_MULT  21
• Supported since Arduplane 4.2
• It is recommended to use STM32CubeProgrammer to erase MCU and upload firmware.  check this blog 

INAV

• 220A Current sensor on H743-WLITE,  set current_meter_scale = 150
• 1k:20k voltage divider for battery voltage sense on H743-WLITE, set vbat_scale = 2100
• H743-WLITE is not supported by INAV4.1 downloaded from configurator. pls download inav_4.1.0_MATEKH743_42688 from Mateksys website.
• Starting with INAV5.0, you may download firmware directly from INAV configurator.

Others

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