The jrk 12v12 motor controller is a highly configurable brushed DC motor controller that supports four interface modes: USB, logic-level serial, analog voltage, and hobby radio control (RC).
I have to admit that Pololu did a real good job with this jerk. I mean jrk. Yeah, I don't know why it's called that either... Regardless of the name, the Jrk 12V12 has a fantastic feature set, and some nice support software. Here's the highlights as we see them:
WOW - that's a huge bundle of features for a compact unit measuring only 1.35" x 1.85"!
So what make is so superior to other models of motor driver units?
The only serious limit to this unit is that it is a single motor driver. Not dual. So if you want to drive a robot, you'll need one of these per motor. But with this feature set, it'll be very easy to work with!

The jrk ships with a 14×1 straight 0.100" male header strip and two 5mm, 2-pin terminal blocks. To provide maximum flexibility, none of these parts are soldered to the board.
For the most compact installation, you can solder wires directly to the jrk pads themselves and skip using the included hardware. The included hardware allows you to make less permanent connections. You can break the 14×1 header strip into an 8×1 piece and two 3×1 pieces and solder these strips into the jrk’s I/O pads.
Note: USB cable not included
