iFlight BLITZ Wing H743

iFlight BLITZ Wing H743 is a flight controller designed for aircraft and flying wings, physically consisting of three boards — the flight controller, PDB for power distribution, and a protective cover. The board supports INAV and Ardupilot firmware. Power can be supplied from 2–8S LiPo batteries (7–36V).

At the heart of the flight controller is the STM32H743 processor with ICM-42688-P gyro and SPL06-003 barometer for altitude measurement. The board features a microSD card slot for storing blackbox logs or map data. The board can be utilized with both digital and analog video transmission. For analog transmission, an OSD chip AT7456E is available for displaying telemetry data in the video and two switchable inputs for analog cameras.

To connect GPS, telemetry, sensors, and other accessories, there are 8 UARTs available. The board also allows for the connection of an external airspeed sensor, which enhances airspeed calculation for fixed-wing and flying wing setups. Connectivity is handled through a combination of connectors and a pin header.

The PDB board manages power distribution to the entire assembly. Five groups of solder pads for regulators ensure power distribution to the motors even in multi-motor configurations. It includes a 5V@2.5A BEC for powering the flight controller and receiver, a 9V@2.5A BEC for the video transmitter or other electronics, and an adjustable 5/7.4/8.4V@6A servo BEC — the voltage selection supports standard 5V servos as well as stronger servos requiring 7.4 or 8.4V without needing an external converter. The integrated current sensor covers a range of 0–176A (continuous 100A, peak 160A).

The mounting hole pattern is 30.5×30.5mm, with a total weight of the assembly being 35g.
