iFlight BLITZ Mini F745 Flight Controller

The iFlight BLITZ Mini F745 is a high-performance flight controller built for compact sub-250g quads, cinewhoops, and lightweight freestyle builds. Driven by the powerful STM32F745 processor and an ICM42688P gyro, it handles complex Betaflight PID loops, high-frequency ESC communication, and dynamic filtering without CPU overload.

Key features

• STM32F745 MCU provides extensive processing headroom for bidirectional DShot and aggressive filter settings.
• ICM42688P gyro delivers low-noise, locked-in flight characteristics.
• Dedicated plug-and-play ports for rapid, solder-free integration with digital HD VTX systems and 4-in-1 ESCs.
• Onboard 5V and 9V BECs efficiently power receivers, GPS modules, and digital video transmitters.

Specifications

• MCU: STM32F745
• Gyro: ICM42688P
• Mounting Size: 20x20
• Input Voltage: 2-6S
• Supported Firmware: Betaflight
• Barometer: None

This flight controller is an ideal brain for 3-inch to 5-inch frames lacking 30.5x30.5 mounting space, giving builders the processing power and connectivity of a full-sized board in a much smaller footprint.
