SEQURE H743 V2 ICM42688P FC 4-8S Dual BEC
The SEQURE H743 V2 ICM42688P FC 4-8S Dual BEC gives your FPV drone the power of an H7 processor and room to grow. It handles anything from a 4S freestyle quad to an eight-motor 8S build, so you will not outgrow it when your next frame gets bigger. Plug-in connectors for digital and analog video, two mounting patterns and your choice of firmware mean less soldering, fewer compromises and more time in the air.
SEQURE H743 V2 ICM42688P FC 4-8S Dual BEC — H7 Power for Builds with Up to Eight Motors
The SEQURE H743 V2 ICM42688P FC 4-8S Dual BEC is a flight controller with an STM32H743 processor running at up to 480MHz, built for FPV drones powered by 4-8S LiPo or LiHV packs. It drives up to eight motors, so besides a classic quad it also handles X8 builds. On board you get an ICM-42688-P gyro, a BMP280/DPS310/DPS368 barometer, an AT7456E chip for analog OSD and 16MB of blackbox memory. Two BECs supply 5V/2.5A and 10V/2A, and plug-in connectors take a DJI O3, O4 or O4 Pro air unit or an analog video transmitter directly. The board has six UARTs, an ESC telemetry input and a USB-C port, and runs Betaflight (preinstalled), INAV and ArduPilot. The 36.5x36.5mm board weighs 7.3g and fits both the 20x20mm and the 30.5x30.5mm mounting pattern.
Fast Control Response
The STM32H743 processor runs at up to 480MHz. SEQURE points to it as the source of the rapid control response of this flight controller.
Precise Attitude Sensing
The ICM-42688-P gyro senses the attitude of the drone precisely. According to SEQURE, this gives stable control and improves the reliability of the whole system.
Flight Data Recorded and Displayed
A barometer, an AT7456E OSD chip and a 16MB blackbox are all on board. The blackbox records flight data for later analysis, and the OSD shows flight information on the analog video feed.
Up to Eight Motors
Outputs M1-M4 are on the ESC connector and M5-M8 on separate solder pads, where the manufacturer's diagram connects a second ESC. That makes an X8 build straightforward.
Plug-In Video System
Plug-in connectors and a dedicated 10V BEC let a DJI O3, O4 or O4 Pro air unit or an analog video transmitter plug straight in. Bridge the matching pads to select 5V or 10V on the VTX port. With neither pair bridged, the port gives no voltage.
Six UARTs for Your Peripherals
Six UARTs cover the devices most FPV drones need. SEQURE recommends this port layout.
- UART1: receiver
- UART2: video transmitter (VTX)
- UART4: free for any device
- UART6: GPS
- UART7: DJI O3/O4/O4 Pro
- UART8: ESC telemetry
ArduPilot uses the same assignment by default, so the ports are ready to go after flashing.
SEQURE H743 V2 ICM42688P FC 4-8S Dual BEC Key Features
Wide Power Range
The board accepts 4-8S LiPo and LiHV packs. One flight controller covers builds from 4S up to 8S, so it can stay with you as your drones get bigger.
Two Mounting Patterns
The mounting holes fit both the 20x20mm and the 30.5x30.5mm pattern, with Φ4mm holes for M3 grommets. You can mount it in a frame or stack made for either size.
Low Weight
The board weighs just 7.3g. It adds next to nothing to the take-off weight of your drone.
Firmware of Your Choice
Betaflight comes preinstalled, and the board also runs INAV and ArduPilot. Fly freestyle on Betaflight or use GPS-assisted flight modes in INAV and ArduPilot.

SEQURE H743 V2 ICM42688P FC 4-8S Dual BEC Wiring Diagram
The manufacturer's diagrams show how to connect an LED strip, an analog camera, a second ESC, a buzzer, GPS modules and video systems to the solder pads, and the ESC, a receiver, a video transmitter and DJI or Vista/Link air units to the SH1.0 connectors. If you do not use the DJI FPV remote controller, do not connect the SBUS wire to the flight controller.
