Overview
Kpower P0300 is a servo motor designed for compact robotic actuation and RC-style control. It is labeled as a “digital servo” and uses a DC brushed motor with a potentiometer position sensor, plastic gear train, and a 3-wire servo interface. Control protocol support is listed as PWM | TTL | RS-485, with a working frequency of 50 ~ 333 Hz (promotional material also mentions compatibility to 50–300 Hz high-frequency signals).
