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 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.
