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


  • ArduPilot Firmware:
  • INAV is expected to support H743 in 2.6.
  • H743-SLIM has betaflight firmware preloaded for QC
  • BetaFlight target is not on the Github, pls download BetaFlight firmware 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.   Disable full chip erase when flashing,  then reset to default in Mission Planner after flashing.
  • It is highly recommended to use STM32CubeProgrammer to erase MCU and upload firmware
