What is new on the H743-slim V3

• ICM42688-P+ICM42605 instead of MPU6000+ICM42605

• Other functions, layout and components are same as previous board version.

• H743-slim 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-slim-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
