Analogue Feedback Micro Servo - Plastic Gear

This Feedback Micro Servo adds position sensing to a compact hobby servo by exposing the potentiometer output, making it ideal for robotics, motion tracking, and projects that need real-time feedback on servo position.

It looks like a micro servo, it acts like a micro servo, but it's more than just a micro servo! We got a factory to custom-make these classic 'micro' sized hobby servos with a twist - the feedback (potentiometer wiper) line is brought out to a fourth white wire. You can read this wire with an analogue input such as those on an Arduino, to get the servo's position. That information can be used in robotics to improve stability or even allow 'recording' of servo motion.

Note that the default servo pulse widths (usually 1ms to 2ms) may not give you a full 180 degrees of motion. In that case, check if you can set your servo controller to custom pulse lengths and try 0.75ms to 2.25ms. You can try shorter/longer pulses but be aware that if you go too far you could break your servo!

Comes with a range of horns as seen in photos.
