Pololu G2 Simple Motor Controllers

The Simple Motor Controllers are versatile, general-purpose single-channel motor controllers for brushed, DC motors. Wide operating voltage ranges and the ability to deliver up to several hundred watts in a small form factor make these controllers suitable for many motor control applications. With a variety of supported interfaces—­USB for direct connection to a computer, TTL serial and I²C for use with embedded systems, RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC), and analog voltages for use with a potentiometer or analog joystick—­and a wide array of configurable settings, these motor controllers make it easy to add basic control of brushed DC motors to a variety of projects. A free configuration utility for Windows simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

The table below lists the all of the members of the Simple Motor Controller family and shows the key differences among them, including the original SMCs with green PCBs. The newer G2 (blue) SMCs can generally be used as drop-in replacements for the originals, which are not recommended for new designs (they are only included in the table below for comparison purposes).
