iFlight SucceX-D Mini F7 2-6S TwinG FC (ICM20689)

The iFlight SucceX-D Mini F7 TwinG is a 20x20mm flight controller built for DJI's digital FPV system, with a 6-pin port that plugs the Air Unit straight in on the included harness. Twin ICM20689 gyros, offset 90 degrees from each other, let Betaflight blend both signals into a cleaner gyro trace for tight 3-inch to 5-inch digital builds.

Key features

• TwinG dual ICM20689 gyros reduce noise and oscillation across the throttle range without adding filter delay.
• Direct 6-pin DJI Air Unit port and 8-pin 4-in-1 ESC port cut down on manual soldering.
• 216MHz STM32F722 MCU with 32MB blackbox handles Betaflight's heavier filtering and logging.
• Five UARTs and USB-C cover GPS, ELRS/Crossfire receivers and telemetry on one board.
• Dual BEC outputs (5V 2.5A and 9V 2.5A) power flight electronics and the VTX/camera separately.

No barometer is fitted, so altitude hold relies on GPS on supported firmware; the 20x20mm footprint and DJI-ready wiring make this a straightforward swap into existing digital 3-inch to 5-inch stacks.
