Technical Highlights

H743 Processing and Dual IMUs

The H743-WING V3 combines a 480 MHz STM32H743VIT6 MCU with an ICM42688-P on SPI1 and an ICM42605 on SPI4. The V3 IMU configuration should be distinguished from earlier H743-WING revisions.

Fixed-Wing-Oriented Connectivity

Seven UARTs, two I2C buses, one CAN interface, a SPI3 breakout and 13 PWM outputs provide connection options for aircraft control and peripheral integration.

Onboard Sensing and Video Functions

The controller includes a DPS310 barometer, AT7456E OSD, MicroSD blackbox slot and switchable dual camera inputs.

Integrated Power Distribution

The board accepts 8–36 V DC input for 3–8S LiPo systems. Its integrated power distribution includes 5 V, selectable 9 V/12 V and configurable Vx outputs for the appropriate connected loads.

Selection and Integration Notes

Confirm that the aircraft has space for the 54 × 36 × 13 mm board; 30.5 × 30.5 mm describes the mounting pattern only.
Select firmware for the MATEKH743 target and verify the installed board revision before flashing.
Check each peripheral's voltage and current requirements against the selected BEC output before wiring.
Confirm the exact supplied accessories and connector set during quotation.

FAQ

What is the difference between the H743-WING V3 and earlier revisions?

The V3 uses an ICM42688-P and ICM42605 dual-IMU configuration. Check the physical board revision before selecting firmware or using specifications from an earlier H743-WING version.

Does 30.5 × 30.5 mm describe the board dimensions?

No. It is the mounting-hole pattern. The stated board dimensions are 54 × 36 × 13 mm.

Which firmware target is used?

The specified target is MATEKH743 for ArduPilot and INAV. Confirm the firmware release and configuration appropriate to the H743-WING V3 before flashing.

Does the controller support blackbox logging?

Yes. It has a MicroSD card slot connected through SDIO for blackbox storage.

B2B Procurement FAQ

How can a buyer specify the correct version in an inquiry?

Specify “Matek H743-WING V3” and request confirmation of the board revision, required quantity, intended firmware and accessory configuration during quotation.

Which accessories are included with the supplied unit?

The exact supplied accessories and connector set must be confirmed during quotation; product illustrations alone do not establish the contents of every order.

What are the MOQ, lead time and delivery terms?

MOQ, lead time and delivery terms have not been established by the supplied product evidence and must be confirmed during quotation.
