Jrk 21v3 USB Motor Controller with Feedback (Connectors Soldered)
The Jrk 21v3 is a versatile, general-purpose motor controller that supports a variety of interfaces, including USB. The broad operating range from 5V to 28V and continuous output current of 3A (5A peak) allow this board to control most small 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) allows easy calibration and configuration through the USB port. AUSB A to mini-B cable(not included) is required to connect this controller to a computer.
