Standard hobby servo with a fourth wire (white) that exposes the internal potentiometer wiper for analog position readback. Connects to any analog input (e.g., Arduino ADC) to close a position loop or record motion.
Servo positive supply lead. Adafruit Learn wiring states SERVO POWER wire connects to USB, and product datasheet lists 4.8 V and 6 V operating parameters.
Servo ground lead. Adafruit Learn wiring states SERVO GROUND wire connects to GND.
Servo control signal lead. Adafruit Learn wiring states SERVO SIGNAL wire connects to A1 in the example circuit.
Analogue position feedback from the servo potentiometer wiper. Adafruit states the feedback signal is brought out to a fourth white wire and can be read with an analogue input.
