The Pololu Simple High-Power Motor Controller makes basic control of brushed DC motors easy, with our free Simple Motor Control Center software enabling quick configuration over USB. The controller supports four interface modes: USB, TTL serial, analog voltage, and hobby radio control (RC). This version operates from 5.5 to 40 V and is efficient enough to deliver a continuous 23 A without a heat sink. It ships with the power capacitor and connectors included but not soldered in, allowing for custom installations.
