The Simple High-Power Motor Controller 18v15 makes basic control of brushed DC motors easy, with the free Simple Motor Control Center software enabling quick configuration over USB. The controller supports four interface modes: USB, TTL serial, analogue voltage, and hobby radio control (RC). This version operates from 5.5 to 30 V and is efficient enough to deliver a continuous 15 A without a heat sink. It ships with the power capacitor and connectors installed as shown.

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 analogue voltages for use with a potentiometer or analogue 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 the initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

  • Absolute max voltage - 30V
  • Recommended max voltage - 24 V
  • Max continuous current w/o heat sink - 15A
  • Dimensions - 5.3 x 2.8 cm
  • weight - 7g
  • 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 the controller model
  • Four communication or control options:
  1. USB interface for direct connection to a PC.
  2. Logic-level (TTL) serial interface for direct connection to microcontrollers or other embedded controllers.
  3. Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller.
  4. 0–3.3 V analogue voltage interface for direct connection to potentiometers and analogue joysticks.
  • Simple configuration and calibration over USB with a free configuration program (Windows 8, 7, Vista, Windows XP, and Linux compatible).
  • 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 analogue 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.#
