Product overview
The iFlight BLITZ F7 Stack (E55 4-IN-1 ESC) combines a BLITZ F7 V1.2 flight controller with a BLITZ E55 four-in-one ESC for recreational drone use. The flight controller pairs an STM32 F722 MCU with an ICM42688 gyro, DPS310 barometer and AT7456E OSD chip. Its 32MB Blackbox flash, six UARTs and four motor outputs with an SH1.0 connector support the control electronics, while indicator LEDs provide visual debugging. A plug-and-play DJI HD VTX connector requires no soldering, and the stack incorporates an LC filter.
The E55 ESC accepts 2-6S LiPo input and provides 55 Amps constant current and 65 Amps burst current. It includes a current sensor and has no BEC; the flight controller provides 5V 2.5A and 9V 2A BEC outputs. Both boards use 30.5*30.5mm mounting patterns with 4mm holes. Supplied equipment includes the flight controller, ESC, silicon grommets and an F7 flight-controller wire harness. On a 7-10 inch drone, add an additional capacitor to prevent overloading the ESC’s onboard capacitor. The product is for fun purposes only and does not support autonomous flight.
