iFlight BLITZ H7 Pro Flight Controller

The iFlight BLITZ H7 Pro is a high-voltage flight controller built around the STM32H743 MCU (upgraded from the original F722), supporting input up to 12S and ArduPilot firmware alongside Betaflight. A dual-sided shield protects the board from interference and debris while still allowing quick SD card access.

Key features

• STM32H743 MCU with a high-voltage DC-DC buck converter rated to 100V for reliable power delivery at high cell counts
• ICM42688P gyro and integrated barometer for precise attitude tracking and altitude hold
• Dedicated connector for digital HD systems including DJI O3, Walksnail Avatar and Caddx Vista
• SD card blackbox logging for larger-capacity flight data recording than fixed onboard flash
• Dual-sided shielding protects the board while keeping the SD card accessible for quick swaps
