Matek Flight Controller H743-SLIM V3

Another great board from Matek which can be used with ArduPilot, Betaflight, and will soon support INAV. Comes with dual gyro, Barometer, 7 UARTS, 13 PWM outputs, OSD and more.

Note: The V3 uses the IMU ICM42688P, ICM42605 instead of the IMU MPU6000, ICM42605 that was used on the V1.5. Nothing else has changed.

FC Firmware:

• ArduPilot(ChiBiOS): MATEKH743
• BetaFlight: MATEKH743
• INAV: MATEKH743

Physical:

• Mounting: 30.5 x 30.5mm, Φ4mm with Grommets Φ3mm
• Dimensions: 36 x 36 x 5 mm
• Weight: 7g

Tips:

• ArduPilot wiki  H7 will not initialize with Ardupilot firmware
• H743 is supported by INAV3.0.1 or higher.
• H743-SLIM has betaflight firmware preloaded for QC
• BetaFlight: Target MATEKH743 is supported since 4.3,  pls download BetaFlight firmware 4.2.x from our website.
• If you flash ArduPilot firmware via BetaFlight configurator.  there is a known issue that flash process will freeze at 50% if “full chip erase” is selected. It is highly recommended to use STM32CubeProgrammer to erase MCU and upload firmware. More info here.
• ArduPilot: Crossfire support only exists in “latest” 4.1, not stable 4.0.x,  if you load “latest” then Set  SERIAL7_PROTOCOL = 23,  RSSI_TYPE = 3
• INAV: SD card and MSC mode for H743 is supported by INAV 4.0 or newer.
• Known issue: Motor 7 will not spin with BetaFlight 4.2.x and OCTO X8 mixer if RPM filter is enabled. Pls set dshot_bidir = OFF,  or use latest BetaFlight 4.3.0
