The iFlight BLITZ F7 Stack (E55 4-IN-1 ESC) is a sophisticated component designed for enhancing the performance and reliability of drones, particularly those ranging from 7 to 10 inches. This stack features an improved circuit design that incorporates superior components, resulting in reduced electrical noise. It is equipped with a DJI HD VTX Connector, which facilitates a plug-and-play setup, eliminating the need for soldering. Additionally, the flight controller includes indicator LEDs that assist in visual debugging, and an LC filter is integrated to further enhance performance.

The flight controller is powered by an STM32 F722 MCU and features the ICM42688 gyroscope, which was updated on January 11, 2024. It also includes a DPS310 barometer and an AT7456E OSD chip, with a substantial 32MB of Blackbox flash memory. The controller supports six UARTs, allowing for versatile connectivity options, including motor outputs and I2C serial communication. It is compatible with Smartaudio and IRC Tramp VTX protocols and includes a built-in LED controller and beeper pad.

The ESC component of the stack supports a 2-6S lipo input and is driven by a G071 MCU. It is capable of handling a constant current of 55 Amps and a burst current of 65 Amps. The ESC supports various protocols such as DShot150, DShot300, DShot600, MultiShot, and OneShot, providing flexibility for different drone configurations. The stack’s design includes a current sensor, although it does not feature a BEC.

Note: When using this ESC on a 7-10 inch drone, it is advisable to add an additional capacitor to prevent overloading the onboard capacitor of the ESC.
