H7 controller for high-I/O FPV and autonomous builds
The H743-SLIM V4 is a 30×30 flight controller built around the STM32H743 processor. It offers dual ICM42688P IMUs, a DPS368 barometer, CAN, seven UARTs and a broad set of PWM and analog connections for builds that outgrow a basic F4 controller.
Key specifications
- Processor: STM32H743VIH6, 480MHz, 1MB RAM and 2MB flash
- Sensors: dual ICM42688P IMUs plus DPS368 barometer
- Power: 6–36V input (2–8S LiPo), TVS protection and 5V BEC rated 2.5A continuous
- Interfaces: seven UARTs, two I²C buses, CAN, SPI3 breakout, USB-C and microSD logging
- I/O: 13 PWM-capable outputs and six ADC inputs
- Video: AT7456E analog OSD with dual-camera switching
- Mounting: 30.5×30.5 mm; board size 36×36×5 mm; approximately 7g
- Firmware targets: ArduPilot, Betaflight and INAV use the MATEKH743 target
Integration guidance
This controller has no built-in current sensor, so an external sensor is required when current monitoring is needed. Confirm connector pinouts, BEC loading and firmware target before powering the airframe. Use the CAN and UART allocation plan before final wiring to keep GPS, telemetry, digital video and peripheral connections serviceable.
Availability note: The manufacturer marks this model end-of-life. Contact 100drone before ordering to confirm an available unit or a current compatible replacement.
