Pololu Jrk 21v3 USB Motor Controller with Feedback

Description

The jrk 21v3 is a versatile, general-purpose motor controller that supports a variety of interfaces, including USB. The broad operating range from 5 V to 28 V and continuous output current of 3 A (5 A 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. Key improvements over competing products and earlier Pololu motor controllers with feedback include: Note: A USB A to mini-B cable (not included) is required to connect this controller to a computer. The jrk 21v3 is the smaller of two jrk motor controllers. For a higher-power version, see the jrk 12v12 . The jrk 21v3 is available in two versions: “fully assembled” with terminal blocks and 0.1? male header pins pre-installed (left picture above), and connector-free (right picture above). The connector-free version includes a straight 0.1? breakaway male header strip and two 3.5mm, 2-pin terminal blocks , but these parts are not soldered to the board, which allows for custom installations. The three mounting holes are intended for use with #2 screws (not included).
