Pololu FEETECH Sub-Micro Servo FS0403-FB with Position Feedback

The FS0403-FB is a specialized variant of the FEETECH FS0403 sub-micro analog servo, featuring a unique feedback potentiometer accessible via a green wire. This addition allows for direct measurement of the output angle, enabling users to verify when the servo reaches its intended position or to detect any obstructions. This feature supports advanced closed-loop control from your main controller.

Perfect for robotics enthusiasts and engineers, this servo works seamlessly with standard RC servo pulses, offering an operating angle of approximately 120° within a pulse range of 900 µs to 2100 µs. For those seeking greater flexibility, the pulse range can be extended, potentially achieving a 180° range with a pulse range of 650 µs to 2500 µs, although results may vary between units.

The servo's connectivity is straightforward with a 3-wire cable for signal, power, and ground, ending in a JR-style connector compatible with Futaba systems. The feedback wire, approximately 15 cm long, is compatible with standard 2.54 mm male header pins, providing easy integration into various projects.

This servo is ideal for applications requiring precise control and feedback, such as robotic arms, custom drones, or automated systems. However, caution is advised as stalling or back-driving can lead to damage, a common consideration with hobby servos. With its enhanced feedback capabilities, the FS0403-FB offers a versatile solution for both hobbyists and professionals seeking precision and reliability in their projects.
