The Yokomo USB Servo Programmer is a compact dongle-style device that connects to a PC via USB to configure and adjust settings on compatible Yokomo SP-02D and SP-03D digital servos. It allows hobbyists to fine-tune servo parameters such as direction, speed, and neutral point through software rather than manual adjustment. This is the factory Yokomo programming tool for those running supported Yokomo digital servos across their lineup of touring cars, drift cars, and buggies.
