Hardware Overview
The ServoBoard is designed for flexibility. You can inject power via the JST-GH connectors or the solder pads, and route PWM signals from your Flight Controller (FC) directly to the signal pads.
1. Signal Input (Control)
The board receives PWM signals from the Flight Controller via a standard JST-GH 5-Pin connector located on the side. This connects directly to your FC's servo rail or PWM breakout.

2. Power Input (High Current)
Power is injected via two parallel JST-GH 4-Pin connectors. These are designed to mate directly with AeroBuck modules.
Ports: 2x JST-GH 4-Pin (Parallel/Passthrough)
Usage: Connect one port to the power source (AeroBuck). The second port can be used to daisy-chain power to another ServoBoard or StrobeIT driver.
