CHF39.88

This powerful motor controller makes basic control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC). This version offers a wide 6.5 V to 30 V operating range and can deliver continuous output currents up to 15 A without a heat sink.

This version ships with soldered header pins and terminal blocks.

The Simple Motor Controllers are versatile, general-purpose single-channel motor controllers for brushed, DC motors. Wide operating voltage ranges 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 and I²C 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. A free configuration utility for Windows simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

The SMC G2 18v15 operates from 6.5 V to 30 V and can deliver a continuous output current of 15 A without a heat sink. Note that 30 V is the absolute maximum for this controller; the maximum recommended operating voltage is 24 V, and the maximum recommended nominal battery voltage is 18 V.

Key features of the SMC G2 family

  • Simple bidirectional control of one brushed DC motor
  • Five communication or control options:
  • USB interface for direct connection to a PC
  • Logic-level (TTL) serial interface for use with a microcontroller
  • I²C interface for use with a microcontroller
  • Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller
  • 0 V to 3.3 V analog voltage interface for direct connection to potentiometers and analog joysticks
  • Simple configuration and calibration over USB with a free configuration program for Windows
  • Reverse-voltage protection
  • Hardware current limiting with a configurable threshold
  • Current sensing

Additional features of the SMC G2 family

  • Adjustable maximum acceleration and deceleration to limit electrical and mechanical stress on the system
  • Adjustable starting speed and maximum speed
  • Option to brake or coast 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 1.13 kHz to 22.5 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
