Physical
- Mounting
- 20 x 20mm/Φ3mm with Silicon Grommets
- 20 x 20mm/Φ2mm with Silicon & Brass Grommets
- Dimensions: 36 x 28 x 6.5mm
- Weight: 7g
Including
- 1x H743-MINI
- 6x Silicon grommets M4 to M3
- 6x Brass grommets M3 to M2
- 1x JST-SH1.0_8pin cable, 5cm
- 2x JST-SH1.0_8pin connectors
- ArduPilot Firmware
- H743 is supported by INAV3.0.1 or higher.
- H743-MINI 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 http://www.mateksys.com/?p=6905
- 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
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
