Pololu Jrk G2 Motor Controllers with Feedback
With integrated support for analog voltage or tachometer (frequency) feedback, the Jrk family of motor controllers makes it easy to add closed-loop control of speed or position (but not both!) of a single brushed DC motor to a wide range of applications. These versatile, general-purpose modules support a variety of high-level control interfaces: USB for direct connection to a computer, TTL serial and I²C for use with a microcontroller, RC hobby servo pulses for use in an RC system, and analog voltages for use with a potentiometer or analog joystick. They also offer many settings that can be configured using our free configuration software utility. This software simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.
