Analog Feedback Standard-Size Servo
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.
Pinout
- Servo power
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.
Type · powerVoltage · 4.8V to 6V servo supply, source-backed by Adafruit product datasheet parameters - Servo ground
Servo ground lead. Adafruit Learn wiring states SERVO GROUND wire connects to GND.
Type · groundVoltage · 0V - Servo signal
Servo control signal lead. Adafruit Learn wiring states SERVO SIGNAL wire connects to A1 in the example circuit.
Type · signal - Feedback white wire
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.
