Details

The jrk 21v3 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). The controller can be used with feedback for closed-loop speed or position control, or it can be used without feedback as an open-loop speed control. The continuous output current is approximately 3A in the recommended operating range of 8-28V, with derated performance down to 5V and transient protection to 40V. The board ships with connectors installed as shown (no soldering required). The jrk 21v3 ships full assembled with terminal blocks and 0.1” male header pins pre-installed. 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.
