Details

The jrk 12v12 is a versatile, general-purpose motor controller that supports a variety of interfaces, including USB. The 6 V to 16 V operating range and high continuous output current of 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) allows easy calibration and configuration through the USB port. The jrk ships with a straight 0.1” breakaway 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 header strip into smaller pieces, such as an 8x1 piece and two 3x1 pieces, and solder these strips into the jrk’s I/O pads. The three mounting holes are intended for use with #2 screws (not included).

Features
- Four communication or control options:
    USB interface for direct connection to a PC.
    Full-duplex, TTL-level asynchronous serial interface for direct connection to microcontrollers or other embedded controllers.
    Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller.
    0-5V analog voltage interface for direct connection to potentiometers and analog joysticks.
- Two closed-loop feedback options:
    0-5V analog voltage.
    Frequency/tachometer digital input up to 2MHz with 1ms PID period.
   (Open-loop control with no feedback also available.)
- Simple configuration and calibration over USB with free configuration program (Windows 8, Windows 7, Vista, and Windows XP compatible).
- Configurable parameters include:
    PID period and PID constants (feedback tuning parameters).
    Maximum current.
    Maximum duty cycle.
    Maximum acceleration.
    Error response.
    Input calibration (learning) for analog and RC control.
- Optional CRC error detection eliminates communication errors caused by noise or software faults.
- Reversed power protection.
- Field-upgradeable firmware.
- Optional feedback potentiometer disconnect detection.
