iFlight BLITZ Mini F7 V1.1 Flight Controller

The iFlight BLITZ Mini F7 V1.1 is a compact 20x20mm flight controller tailored for sub-250g micro drones, 3-inch cinewhoops, and lightweight 5-inch freestyle frames. Driven by an STM32F722 processor and a BMI270 gyro, it provides ample computing headroom for advanced Betaflight filtering and precise flight dynamics.

Key features

• Plug-and-play connectors for digital HD video transmitters (DJI O3, Caddx Vista) and 4-in-1 ESCs reduce build time and eliminate micro-soldering.
• Six available hardware UARTs easily accommodate a full suite of peripherals including GPS, ELRS receivers, and VTX telemetry.
• Integrated 16MB Blackbox flash memory simplifies PID tuning and resonance analysis.
• Robust 5V/2.5A BEC effortlessly powers demanding receivers and LED arrays.
• Modern USB Type-C connector handles frequent plugging without the fragility of older micro-USB standards.
