**UPDATE** This is Version 3

  • V3,  IMU ICM42688P, ICM42605, PWM 1~8, 10~11


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


  • 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


  • 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.


  • 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
