a comprehensive set of programmable motor control functions.
The TETRIX MAX DC Motor Expansion Controller features the following:
• 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.
• Has two H-bridge outputs to control the speed and direction of two DC motors
• Includes two quadrature encoder input ports
• Additional power and expansion ports support daisy chain configurations.
• Can be connected to the LEGO® EV3 Brick and National Instruments’ myRIO. Software blocks can be downloaded
