AGFRC IB53BHU is a standard size servo, providing access to feedback potentiometer through the additional fourth orange wire, which is capable to measure the output angle directly.
With the position feedback function, you can ensure the servo has reached its designated position or detect any potential impediments, of course, this allows additional closed-loop control from your controller. Enable for more complex robotics or industry applications, such as determining when the servo has reached its target, detecting when the output is blocked, or implementing your own higher-level closed-loop position control.

Features
Medium aluminum case
Long lifespan brushless motor
Using typical RC servo commands for operation

Help to implement close-loop position control
Suitable for robotics, industry, interactive artwork, small-scale animatronics etc.
Note: USB servo programmer is not included, if need it, please search the Asin: B09NR1KPM6
