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. Note that the information on this page is specific to the newer SMC G2s, which can generally be used as drop-in replacements for the original SMCs with green PCBs. The original SMCs are not recommended for new designs, and they are only included in the table below for comparison purposes.

Details for item #1367
The SMC G2 24v12 operates from 6.5 V to 40 V and can deliver a continuous output current of 19 A without a heat sink. Note that 40 V is the absolute maximum for this controller; the maximum recommended operating voltage is 34 V, and the maximum recommended nominal battery voltage is 28 V.
If you need to identify which version you have, you can just plug it into a computer through USB and the SMC software will tell you. For quick visual identification without a computer, you can distinguish this version from the identically sized SMC G2 18v25 by the number 100 on top of the tall silver electrolytic capacitors.
This version has header pins and terminal blocks included but not soldered, so soldering is required to use it.

Included hardware
The SMC ships with a 0.1" breakaway male header strip and two 2-pin 5mm terminal blocks. You can solder the terminal blocks to the four large through-holes to make your motor and motor power connections (see Pololu's short video on terminal block installation), or you can solder a couple of 2-pin pieces of the 0.1" header strip into the smaller through-holes above and below these larger holes.
Pieces from the 0.1" header strip can be soldered into the small holes on the logic connection side of the board to enable use with solderless breadboards, perfboards, or 0.1" connectors. For the most compact installation, you can just solder wires directly to the holes.
Note: A USB A to Micro-B cable (not included) is required to connect this controller to a computer.

This video demonstrates the versatility of the Simple Motor Controller by showing how it can be controlled directly from the analog output of a Sharp analog distance sensor—there is no intermediate control board and no programming involved. The unit in the video is one of Pololu's original SMCs, but the newer SMC G2s have the same capabilities. For more information on this example, including the SMC settings file and a list of parts used, see Pololu's blog post about the demo.
Comparison to the original Simple Motor Controllers
The SMC G2 family features a number of improvements compared to Pololu's original Simple Motor Controllers with green PCBs:
The SMC G2 controllers have the same pin arrangements as the original SMCs, so Pololu should be usable as drop-in replacements in typical applications, though note that the minimum operating voltage is a little higher for the G2 versions (6.5 V vs 5.5 V for the originals). The SMC G2 serial protocol is compatible with (and generally a superset of) the original SMC serial protocol, so in most cases, serial interface software running on a microcontroller or computer will not need to be modified to work with a SMC G2.
