iFlight BLITZ Wing H743 Flight Controller

The iFlight BLITZ Wing H743 is a flight controller engineered specifically for fixed-wing aircraft, flying wings, and VTOL platforms. Built around the STM32H743 MCU running at 480MHz, it provides the processing bandwidth and memory required for complex autonomous navigation and mapping tasks in INAV or ArduPilot.

Key features

• Dedicated fixed-wing layout with grouped PWM outputs and header pin pads for direct servo and motor wiring.
• Integrated barometer enables accurate altitude hold and autonomous waypoint flights.
• Onboard MicroSD card slot provides extensive Blackbox logging for tuning and mission telemetry analysis.
• Independent BEC circuits isolate sensitive flight controller logic from high-current servo voltage spikes.
• Multiple hardware UARTs support the simultaneous connection of GPS modules, compasses, digital HD video transmitters, and telemetry radios.
