TETRIX MAX Continuous Rotation Servo enables precise movements of robot designs. Unlike other servos that have a limited range of motion, this servo rotates continuously in either direction – as needed for wheels. This high-quality servo is designed with a wide neutral dead band to eliminate the “creep” that occurs in many other continuous rotation servos. Dual ball bearings on the output shaft ensure long-lasting performance.

Note: This servo does not have position feedback.

This motor controller connects to the PRIZM expansion port, enabling users to control up to two additional 12-volt DC motors. Up to four motor controllers can be connected to the PRIZM expansion port. There are two H-bridge outputs to control the speed and direction of two DC motors and two quadrature encoder input ports. Additional power and expansion ports support daisy-chain configurations.

Supported programming languages include Arduino and EV3. The motor controller can be connected to the LEGO EV3 Brick. Software blocks can be downloaded from the Resources tab below.

TETRIX MAX DC Motor Mount has an increased number of attachment holes, making this two-piece DC motor mount more flexible. Mount a motor between or alongside channels, as well as on top of them.
