The Pololu Jrk G2 19A 6.5-30V USB Motor Controller with Feedback makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using a free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC). This version offers a wide 6.5 V to 30 V operating range and can deliver continuous output currents up to 19 A without a heat sink.

With integrated support for analog voltage or tachometer (frequency) feedback, the second-generation G2 family of Jrk 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 variety of projects.
