#### Step 1: Connect Control Signals

Use a JST-GH 5-Pin to JST-GH (or DuPont) cable to connect the ServoBoard Signal Port to your Flight Controller's PWM output rail. Ensure the `GND` pin is connected to maintain a common ground reference.

#### Step 2: Inject Power

Connect an AeroBuck-5 (for 5V) or AeroBuck-12 (for HV Servos) to one of the JST-GH 4-Pin power ports on the ServoBoard.

> ⚠️ Warning: Do not power the ServoBoard from the Flight Controller's 5V rail if using high-torque servos. Always use an external BEC/AeroBuck to prevent brownouts.

#### Step 3: Connect Servos

Plug your servos into slots 1–4. The ServoBoard will now route the high-current power from the AeroBuck and the precise PWM signals from the FC to your servos.
