This tiny module can control two motors, 1 A peak each, and you can daisy-chain multiple units to control up to 62 motors with a single serial line. You can also order this controller including a color, printed manual, which is available as a PDF (292k). Overview Pololu’s popular micro motor controller will get your robot running in a snap. The tiny module can individually control two motors, and you can daisy-chain multiple units to control up to 62 motors with one serial line. The new version provides up to 2 A to a single motor, or 1 A each to two motors. The motor supply can be as low as 2 V, making the unit a perfect match for small DC motors. Using one serial output from your microcontroller, you can independently set each motor to go forward or backward at any of 127 speeds, coast, and with the new version, brake. The micro motor controller is compatible with Pololu serial servo controllers and serial motor controllers, so you can control an almost unlimited number of motors and servos with one serial line. For a higher-current model, see Pololu low-voltage dual serial motor controller . Note: The Pololu micro dual serial motor controller comes pre-assembled. However, to use the motor controller in robotics projects, you need to connect it to your own motors and robot controller. Device specifications For complete specifications and information on using the Pololu micro motor controller, see the user’s guide (292k).
