Supports DShot and other protocols for versatility
Includes 8MB blackbox for data logging
Offers plug-and-play DJI HD VTX Connector
The iFlight BLITZ Mini F7 Stack (E55 Mini 4-IN-1ESC) features an enhanced circuit design that incorporates superior components to reduce electrical noise. This product is equipped with a DJI HD VTX Connector, allowing for a plug-and-play experience without the need for soldering. The flight controller includes indicator LEDs to facilitate visual debugging, enhancing the user experience.
The flight controller is built around the STM32 F722 MCU and integrates an ICM42688 gyro and DPS310 barometer. It supports six UARTs and features an OSD chip for on-screen display capabilities. The device also includes a blackbox flash memory of 8MB for data logging. The mounting pattern is 20x20 mm with a 4mm PCB hole diameter, and it is designed to accommodate M3 screws with silicon grommets for secure installation.
The ESC supports a 2-6S Lipo input and is capable of handling a constant current of 55 Amps with a burst capacity of 65 Amps. It is equipped with a current sensor and supports various protocols including DShot150, DShot300, DShot600, MultiShot, and OneShot. The ESC firmware is based on BLHeli 32, ensuring reliable performance.
Note: If the ESC is to be used in the iH3 O3 Frame kit, it is necessary to remove the capacitor after receiving the ESC before installation.
