Simple Motor Controller 18v7 (Fully Assembled)

Description of product


This Simple Controller 18v7 makes basic control of brushed DC motors easy, with free Simple Motor Control Center software enabling quick configuration over USB. This version operates from 5.5 to 30 V and is efficient enough to deliver a continuous 7 A (>30 A peak) without a heat sink. It ships with the power capacitor and connectors installed as shown. With a variety of supported interfaces—­USB for direct connection to a computer, TTL serial for use with embedded systems, RC hobby servo pulses for use as an RC-controlled electronic speed control (ESC), and analog voltages for use with a potentiometer or analog joystick—­and a wide array of configurable settings, these motor controllers make it easy to add basic control of brushed DC motors to a variety of projects. Although this motor controller has many more features than competing products, a free configuration utility (for Windows 7, Vista, Windows XP, and Linux) simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.
