What is new on the H743-mini V3
ICM42688-P+ICM42605 instead of MPU6000+ICM42605
PWM 10 & 11 instead of PWM9 & 10(V1/V1.5)
Other functions. layout and components are same as previous board version.
H743-mini V3 has betaflight_4.3.0 preloaded for QC
ArduPilot
H743-mini-V3 with ICM42688-P is supported by ArduPilot 4.2 or higher.
ICM42688-P is defined as first IMU (IMU0) . ICM42605 is the 2nd (IMU1).
with ArduPilot 4.2. set INS_ENABLE_MASK to 7 or default 127.
It is recommended to use STM32CubeProgrammer to erase MCU and upload firmware. check this blog http://www.mateksys.com/?p=6905
INAV
H743-mini-V3 is not supported by INAV4.1 downloaded from configurator. pls download inav_4.1.0_MATEKH743_42688 from our website.
Starting with INAV5.0. V1/V1.5/V3 will share the same firmware.
BetaFlight
IMU ICM42688-p is supported by BetaFlight 4.3 or higher.
icm42688-p is the first IMU(default). ICM42605 is the second IMU.
Target MATEKH743 in BetaFlight 4.2.x list doesn't support ICM426XX series. You need to flash it with BF4.3_RC or latest
