Product overview

The iFlight BLITZ Mini F7 Stack (E55 Mini 4-IN-1ESC) pairs a BLITZ Mini F7 V1.2 flight controller with a Mini E55 ESC for recreational flight control and motor control. The controller combines an STM32 F722 MCU, ICM42688 gyroscope, DPS310 barometer and AT7456 OSD chip with 8MB of Blackbox flash. Six UARTs and four motor outputs through an SH1.0 connector provide connection options, while a DJI HD VTX connector supports plug-and-play installation without soldering. Indicator LEDs provide visual debugging, and Smartaudio and IRC Tramp VTX control are supported.

The flight controller measures 30.5x27 mm, weighs 5g and uses a 20x20 mm mounting pattern with 4mm PCB holes and grommets for M3 screws. The 11.3g ESC accepts 2-6S LiPo input and is rated at 55 Amps constant and 65 Amps burst. It includes a current sensor and has no BEC. The package supplies both boards, silicon grommets and an F7 flight-controller wire harness. Installation in the iH3 O3 Frame kit requires capacitor removal before fitting the ESC. The stack does not support autonomous flight.
