iFlight BLITZ Mini ATF435+BLITZ Mini E55S FPV Stack

iFlight BLITZ Mini ATF435 & E55S 55A 4-in-1 Stack (20x20mm)

Unleash incredible power in a compact form factor with the iFlight BLITZ Mini FPV Stack. This electronics combo pairs the next-generation BLITZ Mini ATF435 Flight Controller with the robust BLITZ Mini E55S 4-in-1 ESC, creating a powerhouse for FPV drone builds that demand high performance without the bulk. It’s the perfect core for a lightweight 5-inch freestyle FPV drone or a powerful 4-inch racer.

Next-Generation Flight Control

The BLITZ Mini ATF435 flight controller is built around a powerful ArteryTek AT32F435 MCU and the high-performance BMI270 gyro. This combination provides lightning-fast processing and incredibly clean gyro data for a precise and locked-in flight feel. With 6 available UARTs, a built-in DPS310 barometer for accurate altitude readings, and 16MB of blackbox flash for easy tuning, this FC is packed with all the features a modern FPV pilot needs.

Extreme Power in a Mini Stack

The BLITZ Mini E55S ESC is a beast, capable of handling a massive 55A of continuous current (65A burst) on up to 6S LiPo power. This makes it suitable for even the most demanding motors on a compact build. It comes ready for modern performance with support for DShot protocols and Bluejay firmware, which enables advanced features like bi-directional DShot for RPM filtering, resulting in an even smoother and more responsive flight experience.

Key Features:

• Advanced AT32F435 MCU: Delivers lightning-fast processing power for the smoothest, most responsive flight experience with all modern Betaflight features enabled.
• High-Performance BMI270 Gyro: A modern, low-noise gyro providing the clean data needed for a locked-in feel and easier tuning.
• Massive 55A 4-in-1 ESC: Provides an extreme amount of power in a 20x20mm form factor, capable of handling the most demanding motors on up to 6S.
• Bluejay Firmware Compatible: Unlocks modern features like bidirectional DShot and RPM filtering on reliable and affordable BLHeli_S hardware.
• 6 Available UARTs & Barometer: Extensive connectivity for peripherals like GPS, plus a high-precision barometer for accurate altitude readings.
• Compact & Builder-Friendly: The 20x20mm mounting pattern and connectorized design make it perfect for clean, lightweight, and easy-to-assemble drone builds.
