iFlight BLITZ Mini F7 E55 4-IN-1 FPV Stack

The iFlight BLITZ Mini F7 E55 4-IN-1 FPV Stack is a testament to innovation and engineering excellence, designed to elevate the performance of FPV drones with its advanced features and seamless integration. This stack merges the prowess of the BLITZ Mini F7 Flight Controller with the robust E55 4-IN-1 ESC, creating a compact powerhouse for drone enthusiasts. The flight controller boasts an STM32 F722 MCU, BMI270 gyro, and DPS310 barometer, alongside 16MB of flash for blackbox data. It supports six UARTs for extensive peripheral connectivity and includes a DJI HD VTX connector for plug-and-play convenience, eliminating the need for soldering. Indicator LEDs and a comprehensive LED controller enhance its utility, making it a versatile choice for builders.

The ESC component further complements this stack with its support for 2-6S Lipo input, 55A constant current capability, and a peak of 60A. Its G071 MCU ensures smooth and responsive motor control, supported by the latest BLHeli 32 firmware for optimal efficiency and performance. Together, these components offer a refined flying experience, marked by reduced electrical noise and heightened responsiveness.
