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 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.
 
For 24 V applications, we recommend the 24v12 or 24v23 versions. 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.

 

 
Key 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 8, 7, Vista, Windows XP, and Linux compatible).
Note: A USB A to mini-B cable (not included) is required to connect this controller to a computer.

 

 
Additional Features:
  • Comprehensive user’s guide with plenty of connection diagrams and sample code.
  • Adjustable maximum acceleration and deceleration to limit electrical and mechanical stress on the system.
  • Adjustable starting speed, maximum speed, and amount of braking when speed is zero.
  • Optional safety controls to avoid unexpectedly powering the motor.
  • Input calibration (learning) and adjustable scaling degree for analog and RC signals.
  • Under-voltage shutoff with hysteresis for use with batteries vulnerable to over-discharging (e.g. LiPo cells).
  • Adjustable over-temperature threshold and response.
  • Adjustable PWM frequency from 1 kHz to 22 kHz (maximum frequency is ultrasonic, eliminating switching-induced audible motor shaft vibration).
  • Error LED linked to a digital ERR output, and connecting the error outputs of multiple controllers together optionally causes all connected controllers to shut down when any one of them experiences an error.
  • Field-upgradeable firmware.
USB/Serial features:
  • Controllable from a computer with native USB, via serial commands sent to the device’s virtual serial (COM) port, or via TTL serial through the device’s RX/TX pins.
  • Example code in C#, Visual Basic .NET, and Visual C++ is available in the Pololu USB Software Development Kit
  • Optional CRC error detection to eliminate communication errors caused by noise or software faults.
  • Optional command timeout (shut off motors if communication ceases).
  • Supports automatic baud rate detection from 1200 bps to 500 kbps, or can be configured to run at a fixed baud rate.
  • Supports standard compact and Pololu protocols as well as the Scott Edwards Mini SSC protocol and an ASCII protocol for simple serial control from a terminal program.
  • Optional serial response delay for communicating with half-duplex controllers such as the Basic Stamp.
  • Controllers can be easily chained together and to other Pololu serial motor and servo controllers to control hundreds of motors using a single serial line.
RC features:
  • 1/4 µs pulse measurement resolution.
  • Works with RC pulse frequencies from 10 to 333 Hz.
  • Configurable parameters for determining what constitutes an acceptable RC signal.
  • Two RC channels allow for single-stick (mixed) motor control, making it easy to use two simple motor controllers in tandem on an RC-controlled differential-drive robot (you might find our RC servo Y splitter cables useful for connecting two SMCs to a single RC receiver).
  • RC channels can be used in any mode as limit or kill switches (e.g. use an RC receiver to trigger a kill switch on your autonomous robot).
  • 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.
