Notes & 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 http://www.mateksys.com/p=6905
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 or older downloaded from configurator. pls download inav_4.1.0_MATEKH743_42688 from here.
– Starting with INAV5.0, you may download firmware directly from INAV configurator.

If the ESCs you are using don??t have enough capacitors integrated, low ESR electrolytic capacitor is required for reducing ESC noise.
