Matek H743-SLIM V4 Flight Controller
Technical Highlights
H7 Processing with Dual IMUs
The STM32H743VIH6 MCU runs at 480 MHz and is paired with two ICM42688P inertial sensors. The board provides 1 MB of RAM and 2 MB of flash memory.
Onboard Sensing, OSD and Logging
A DPS368 barometer, AT7456E OSD chip and MicroSD card socket support flight sensing, analog video overlay and Blackbox logging.
Flexible Control and Peripheral Connections
The H743-SLIM V4 provides seven UARTs, two I2C buses, one CAN interface, an SPI3 breakout and 13 PWM outputs, including the LED pad.
2–8S Power Input and Switchable Video Supply
The board accepts 6–36 V DC input with TVS protection. It provides a 5 V BEC rated at 2.5 A continuous and a filtered VBAT output rated at 2 A for video equipment.

Integration Notes
Select the MATEKH743 firmware target for the supported ArduPilot, Betaflight or INAV build.
The board has ADC inputs for current-sensor signals but no built-in current sensor.
Check the continuous and maximum ratings separately when planning the 5 V power budget.
Confirm board revision, physical clearance and wiring against the supplied unit before installation.
FAQ
Which firmware target does the H743-SLIM V4 use?
The manufacturer lists MATEKH743 as the target for ArduPilot, Betaflight and INAV. Select firmware appropriate for the board and verify the configuration before flight.
Does this flight controller include a current sensor?
No. The H743-SLIM V4 has no built-in current sensor. Current-sensor ADC inputs are available for use with an external sensor.
What battery input and 5 V output does the board support?
The specified input is 6–36 V DC, corresponding to 2–8S LiPo. Its 5 V BEC is rated at 2.5 A continuous and 3 A maximum.
What changed in the V4 revision?
Compared with the previous board revision, Matek specifies a DPS368 barometer, TVS input protection, a 5 V BEC increased from 2 A to 2.5 A, and a filtered VBAT output increased from 1 A to 2 A.
B2B Procurement FAQ
Is the H743-SLIM V4 currently available?
Matek identifies this model as EOL. Any remaining availability, quantity and lead time must be confirmed during quotation; the archive filename does not establish current stock.
How can the board revision and source be verified?
Request confirmation of the H743-SLIM V4 board marking, revision, product photos and supply source before ordering. Matek has published a warning about counterfeit H743-SLIM V4 boards, so authenticity should be checked for the offered batch.
What are the package contents, MOQ and commercial terms?
The exact supplied package, minimum order quantity, pricing, warranty and delivery terms must be confirmed during quotation. They are not established by the provided archive.
