iFlight BLITZ D25 HD F7 AIO Flight Controller with OSD

The iFlight BLITZ D25 HD F7 AIO is a highly integrated flight controller and ESC board originally designed for the Defender 25 cinewhoop, making it a perfect drop-in replacement or the foundation for custom 2.5-inch to 3-inch 4S builds. It combines an F745 processor and a 20A ESC onto a compact 25.5x25.5mm whoop-style layout, featuring dedicated plug-and-play support for HD digital FPV systems like the DJI O3 Air Unit.

Key features

• Plug-and-play connector for HD VTX systems, eliminating the need to micro-solder your DJI O3, Walksnail, or Caddx Vista unit.
• All-in-one architecture integrates a powerful STM32F745 MCU and 20A ESC to minimize wiring and save frame space.
• Includes 32MB of onboard flash memory for detailed Blackbox flight logging and tuning.
• Robust 5V/2.5A BEC to reliably power external receivers, GPS modules, or other peripherals.
