The jrk 12v12 is a versatile, general-purpose brushed DC-motor controller that supports four interface modes: USB, TTL asynchronous serial, PWM, 0 - 5V analog voltage. The 6 to 16V operating range and high continuous output current (12A, 30A peak) allow this board to control many medium-sized DC brushed motors. Analog voltage and tachometer (frequency) feedback options allow quick implementation of closed-loop servo systems, and a free configuration utility (for Windows 7, Vista, or Windows XP) allows easy calibration and configuration through the USB port.
The jrk 12v12 is the larger of two jrk motor controllers. For a lower-power version that has a wider operating voltage range, see the jrk 21v3.
