The Pololu Jrk G2 21v3 USB Motor Controller w/ Feedback is a compact and versatile module designed for closed-loop speed or position control of a single brushed DC motor. It operates within a voltage range of 4.5 V to 28 V and delivers a continuous output current of 2.6 A, peaking at 5 A without the need for a heat sink. This controller supports various control interfaces, including USB, TTL serial, I²C, analog voltage, and RC, allowing for seamless integration with computers, microcontrollers, and RC systems. The Jrk G2 21v3 features ultrasonic 20 kHz PWM for quieter operation and offers multiple configurable parameters such as PID coefficients, maximum current, and acceleration limits. It includes a 0.1″ breakaway male header strip and two 2-pin 3.5mm terminal blocks for custom installations. The device is equipped with advanced feedback options, reversed-power protection, and field-upgradeable firmware, making it a robust solution for a wide range of motion control applications.
