RB-Pol-153

Pololu 24v23 5.5-40V, 23A Motor Controller

Features:

• Simple bidirectional control of one DC brush motor.

• 5.5 V to 30 V (18v7, 18v15, and 18v25) or 40 V (24v12 and 24v23) operating supply range.

• 7 A to 25 A maximum continuous current output without a heat sink, depending on controller model

• Four communication or control options:

-USB interface for direct connection to a PC.

-Logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded

controllers.

-Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo

controller.

-0–3.3 V analog voltage interface for direct connection to potentiometers and analog joysticks.-

• Simple configuration and calibration over USB with free configuration program (Windows 7, Vista,

Windows XP, and Linux compatible).

The Pololu Simple Motor Controllers are versatile, general-purpose motor controllers for

brushed, DC motors. A wide operating range of up to 5.5–40V 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, 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.

• Battery elimination circuit (BEC) jumper can power the RC receiver with 5 V or 3.3 V. Analog features: • 0.8 mV (12-bit) measurement resolution. • Works with 0 to 3.3 V inputs. • Optional potentiometer/joystick disconnect detection. • Two analog channels allow for single-stick (mixed) motor control, making it easy to use two simple motor controllers in tandem on a joystick-controlled differential-drive robot. • Analog channels can be used in any mode as limit or kill switches.
