The dual serial motor controller
allows any micro-controller or computer with a serial port to drive two
bi-directional DC motors with full 7-bit speed-control. Multiple motor
controllers can be controlled with a single serial line, and they are
compatible with the servo controller above. Also see the micro version
The Pololu dual serial motor controller allows you to
control two DC motors with almost any micro-controller. Using one serial output
from your micro-controller, you can independently set each motor to go forward or
backward at any of 127 speeds.
You can independently control up to 62 motors with a
single serial line by connecting multiple motor controllers to the same line
(make sure to use motor controllers that respond to different motor
numbers). The motor controller is compatible with our serial
16-servo controller and micro dual
serial motor controller, so you can control an almost unlimited number of
motors and servos with one serial line.
You can purchase the motor controller as a kit so you can
assemble it yourself (which requires soldering), or you can purchase a pre-assembled motor controller that is soldered and tested for you.
For a smaller, pre-assembled version of this motor
controller that supports lower voltages, see our micro dual
serial motor controller. Order the version that makes the most sense for
your particular application!
The Pololu dual serial motor controller is a kit; before using
it, you need to assemble the controller by soldering its components onto
its circuit board. You can also purchase an assembled, tested kit. To
use the kit in robotics projects, you need to connect the motor
controller to your own motors and robot controller. For a pre-assembled
version, see our micro dual
