Overview
This board is designed to simplify and harden the connection between modern flight controllers and external motors or servos. It converts JST-GH 1.25 mm PWM outputs from the flight controller into standard 3-row pin headers (GND / V+ / Signal) while providing regulated, selectable servo power in one compact module.
Ideal for UAVs, FPV aircraft, VTOLs, and robotics systems where clean wiring, stable power, and flexible voltage options are critical.
