iFlight Borg F7 Mini Flight Controller (ICM42688)

The iFlight Borg F7 Mini is a high-performance flight controller designed for space-constrained FPV builds, ranging from lightweight freestyle frames to compact cinewhoops. Driven by an F7 processor and the low-noise ICM42688P gyroscope, it delivers fast loop times and accurate attitude sensing to ensure locked-in flight characteristics even in challenging aerodynamic conditions.

Key features

• F7 processor handles complex Betaflight filtering and high PID loop rates without CPU overload
• ICM42688P gyroscope provides excellent electrical noise rejection and precise tracking
• Miniature form factor fits easily into tight frames with limited stack clearance
• Hardware UART support for routing digital VTX telemetry, serial receivers, and GPS modules

Specifications

• Processor: F7
• Gyroscope: ICM42688P
• Supported firmware: Betaflight

This board is an excellent drop-in option for pilots looking to equip a 3-inch or 4-inch micro drone with a dedicated, full-featured flight controller without the bulk of a standard 30.5mm stack.
