Pololu Jrk 21v3 USB Motor Controller with Feedback - Pre-soldered connectors
Versatile, general-purpose motor controller
Designed to control most small DC brushed motors
Two closed-loop feedback options: Analog voltage and tachometer (frequency)
Supports four control interfaces: USB, TTL serial, analog voltage (potentiometer), and hobby radio control (RC)
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 3 A in the recommended operating range of 8 V to 28 V, with derated performance down to 5 V and transient protection to 40 V.
Item Specifics 1 - Jrk 21v3 Controller 1 - 0.1" Male header (Pre-soldered) 2 - 2-pin 3.5mm terminal blocks (Pre-soldered) USB connectivity with emulated serial (COM) port allows direct motor control from a PC. Ultrasonic PWM to eliminate switching-induced motor shaft hum or whine. Robust, high-speed communication protocol with user-configurable error condition response. High internal resolution (12 bits) for smooth and flexible calibration to various input and feedback devices. Current sensing and limiting. Reversed power protection. Field-upgradeable firmware.
