2.3KG Serial Bus Servo (6V) Category_Mechanics and Materials/Tracks the default baud rate isThis is a miniature servo that can be connected in series, which can be controlled individually or in a unified manner through TTL serial communication. The combination of gears of various materials maximizes the mechanical performance of the servo. The low noise and durable plastic gears will be used during high speeds, while at low speeds, the metal gears will be used for improving performance. It features an up to 180 rotation angle in the pulse
