Notes

• The discontinued Batan B2122 is a standout in the micro servo class, offering a robust metal gear train and a feature that sets it apart for advanced robotics: an accessible analog feedback line. This fourth wire, which carries the potentiometer's wiper signal, allows a microcontroller like an Arduino to read the servo's exact position. This capability is invaluable for robotics projects that require closed-loop control, such as building stable walking gaits for small robots, creating record-and-playback sequences for animatronics, or ensuring a robotic arm reaches its target position with high accuracy. This feature transforms the B2122 from a simple actuator into an intelligent motion control component.
• Beyond its feedback capability, the B2122 is a solid performer in its own right. The metal gears provide a significant durability upgrade over typical plastic-geared micro servos, making it suitable for applications that might otherwise strip a standard servo, such as the steering on a micro RC crawler or the control surfaces on a high-performance park flyer. The single ball bearing on the output shaft provides smooth action and reduces slop, contributing to more precise control.
• Even without using the feedback wire, the B2122 serves as a high-quality, durable micro servo for general RC use. It's an excellent choice for small aircraft, helicopters, and cars where reliability is key. However, for the robotics hobbyist and engineer, the B2122's feedback feature opens up a world of advanced control possibilities, making it an exceptionally valuable and versatile component for sophisticated projects.
