New products: more special servos with position feedback
We have expanded our selection of specially modified FEETECH servos that have direct access to the feedback potentiometer through an extra fourth (green) wire! Several months ago, we started carrying similarly modified micro FS90-FB and standard-sized FS5103B-FB servos. Now, our larger selection includes a variety of sizes from compact sub-micro servos all the way up to ultra-high torque giant servos:
- FEETECH Sub-Micro Servo FS0403-FB with Position Feedback
- FEETECH Mini Servo FT1117M-FB with Position Feedback
- FEETECH High-Torque Servo FS5115M-FB with Position Feedback
- FEETECH Ultra-High-Torque, High-Voltage Digital Giant Servo FT5335M-FB with Position Feedback

These new additions are special versions of the normal sub-micro FS0403, mini FT1117M, high-torque standard-size FS5115M, and ultra-high-torque giant FT5335M FEETECH servos.
The feedback voltage, which varies linearly over the servo’s range of motion by a couple of volts, is especially useful for more complex robotic applications that require monitoring the actual servo position. For example, it can be used for determining if the servo is stalled or when it has reached it’s target position. It also allows you to implement your own higher-level closed-loop position control or create servo movements by hand that you can record and play back later.

What kind of signal comes from feedback wire of the FS5115M-FB?
Some servos with feedback have PWM feedback signal.
Does FEETECH's FB servo output static voltage related to the position?
Thanks in advance

As described in the post above, the feedback wire gives direct access to the servo's feedback potentiometer. It is an analog voltage signal, and it varies linearly throughout the servo's range of motion by a couple of volts.
