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.
