{"title":"Analog Feedback Micro Servo - Metal Gear","handle":"analog-feedback-micro-servo-metal-gear","url":"/products/analog-feedback-micro-servo-metal-gear","description":"A metal-geared micro servo with an extra trick — a fourth wire brings out the internal potentiometer feedback signal, letting you read the servo's actual position via an analog input. This feedback capability enables motion recording, playback, and improved stability in robotics applications.\n\nThe servo uses standard hobby servo pulse widths and is compatible with any microcontroller that can generate servo PWM signals. The default 1–2ms pulse range may not deliver a full 180° of motion; try 0.75–2.25ms for extended range, but avoid going too far to prevent damage.\n\nKey Features\n\n\nAnalog Position Feedback – Fourth wire outputs the potentiometer wiper signal for position reading\n\nMetal Gears – Durable metal gear train for reliable, long-lasting operation\n\nMicro Size – Standard micro servo form factor\n\nMotion Recording – Read position data to record and play back servo movements\n\nMultiple Horns – Comes with a range of servo horns\n\n\nSpecifications\n\n\nGear Type – Metal\n\nFeedback – Analog (potentiometer wiper on 4th wire)\n\nWiring – 4 wires (power, ground, signal, feedback)\n\nDefault Pulse Width – 1–2ms (try 0.75–2.25ms for extended range)\n\n\nIdeal For\n\nRobotics with position feedback and stability control\nServo motion recording and playback\nArduino and microcontroller projects\nAnimatronics and interactive builds\n\n\n\nNote: Using pulse widths shorter or longer than the servo's safe range may cause damage. Start with the default 1–2ms range and adjust gradually.\n\n\nPackage Contents\n\n1× Analog Feedback Micro Servo (metal gear)\nAssorted servo horns\n\n\nResources\n\nArduino Record & Play Example Sketch (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":7942,"title":"Default Title","sku":"AF-1450","price":19.0,"compare_at_price":30.83,"on_sale":true,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
