iFlight Blitz ATF435 Flight Controller (Standard & Mini)

The iFlight Blitz ATF435 Flight Controller is engineered for 5-inch freestyle, racing, and long-range cinematic builds, offering a high-performance alternative to traditional F405 chips. Built around the ArteryTek AT32F435 MCU running at a 288MHz clock speed, it delivers substantial processing headroom to run complex Betaflight filtering and high PID loop frequencies smoothly. Available in both Standard (30.5x30.5 mm) and Mini (20x20 mm) formats, it integrates cleanly into anything from compact 3-inch cinewhoops up to full-sized heavy-duty quads.

Key features

• High-speed AT32F435 architecture: Operates at a 288MHz clock speed for superior loop times and advanced Betaflight dynamic filtering.
• Six hardware UARTs: Comprehensive peripheral connectivity for GPS modules, HD digital video transmitters, and external receivers without sharing ports.
• Dual BEC output: Integrated 5V/2.5A and 9V/2A regulators provide stable power for the DJI O3 Air Unit or high-power analogue VTXs.
• Flight data logging: Features integrated flash memory (16MB on Mini, 32MB on Standard) for detailed Blackbox tuning analysis alongside a precision DPS310 barometer.
