Product overview
The iFlight BLITZ Mini F745 Flight Controller supports Betaflight and Ardupilot firmware for recreational flight applications. Its electronics combine an STM32F745 MCU, ICM42688 gyro, DPS310 barometer and AT7456E OSD chip, alongside 16MB of Blackbox flash. An improved circuit design and components reduce electrical noise, while onboard indicator LEDs support visual debugging. The controller measures 30.5*27 mm, weighs 4.8g and uses a 20*20mm/φ4 mounting pattern. It is intended for recreational use only and does not support autonomous flight.
Connectivity includes six UARTs, four motor outputs through an SH1.0 connector, and a plug-and-play DJI HD VTX connector requiring no soldering. Smartaudio and IRC Tramp VTX protocols are supported, with an LED controller and beeper pad also provided. Suggested wiring assigns UART 1 to HD or analog VTX, UART 2 to a receiver, UART 3/4/5 to GPS or other serial sensors, and UART 6 to ESC telemetry. The 5V BEC supplies 2.5A continuously and 3A peak for 15 seconds. The package contains one BLITZ Mini F745 Flight Controller.
