Pololu Simple High-Power Motor Controller 18v25 - PL-1381 info

Pololu Simple High-Power Motor Controller 18v25 is a versatile, general-purpose motor controller for brushed, DC motors. A wide operating range of up to 5.5–30V and the ability to deliver up to several hundred Watts in a small form factor make these controllers suitable for many motor control applications. 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, Pololu Simple High-Power Motor Controller 18v25 makes it easy to add basic control of brushed DC motors to a variety of projects. Although Pololu Simple High-Power Motor Controller 18v25 has many more features than competing products, a free configuration utility (for Windows 8, 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.

We strongly recommend against using the 18v7, 18v15, or 18v25 with 24 V batteries, which can significantly exceed 24 V when fully charged and are dangerously close to the maximum voltage limits of these lower-voltage controllers.

Note: A USB A to mini-B cable (not included) is required to connect this controller to a computer.
