iFlight Blitz ATF435 Flight Controller (Standard & Mini)

The iFlight Blitz ATF435 Flight Controller runs on the ArteryTek AT32F435 MCU, a high-headroom alternative to F405/F722 boards for 5-inch freestyle, racing and long-range builds. It ships in two footprints: Standard (30.5x30.5mm) for full-size quads and Mini (20x20mm) for 3-inch and compact 5-inch builds.

Key features

• AT32F435 MCU with an ICM42688 gyro and DPS310 barometer for clean Betaflight filtering and altitude-aware modes.
• Six hardware UARTs cover GPS, a digital HD VTX and a receiver without sharing ports, plus SmartAudio/IRC Tramp support for analogue VTXs.
• Standard carries a dual 5V/2.5A + 9V/2A BEC for HD air units; Mini runs a single 5V/2.5A rail.
• Onboard blackbox flash logs flight data for PID tuning — 32MB on Standard, 16MB on Mini.
• Four SH1.0 motor output connectors and silicone shock grommets for a solder-light install.
