Tips

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
  • For now, Pls download “latest” ArduPilot firmware for H743-WLITE
  • 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 downloaded from configurator. pls download inav_4.1.0_MATEKH743_42688 from our 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.
