Dettagli

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 40 V operating range and can deliver continuous output currents up to 12 Awithout a heat sink. Male headers and terminal blocks are included but not soldered, allowing for custom installations

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 table below lists the all of the members of the Simple Motor Controller family and shows the key differences among them. Note that the information on this page is specific to the newer SMC G2s, which can generally be used as drop-in replacements for the original SMCs with green PCBs. The original SMCs are not recommended for new designs, and they are only included in the table below for comparison purposes.

The SMC G2 24v12 operates from 6.5 V to 40 V and can deliver a continuous output current of 12 A without a heat sink. Note that 40 V is the absolute maximum for this controller; the maximum recommended operating voltage is 34 V, and the maximum recommended nominal battery voltage is 28 V.

If you need to identify which version you have, you can just plug it into a computer through USB and the SMC software will tell you. For quick visual identification without a computer, you can distinguish this version from the identically sized SMC G2 18v15 by the number 100 on top of the tall silver electrolytic capacitors.

This version has header pins and terminal blocks included but not soldered, so soldering is required to use it.

The SMC ships with a 0.1″ breakaway male header strip and two 2-pin 5mm terminal blocks. You can solder the terminal blocks to the four large through-holes to make your motor and motor power connections (see our short video on terminal block installation), or you can solder a couple of 2-pin pieces of the 0.1″ header strip into the smaller through-holes above and below these larger holes.

Pieces from the 0.1″ header strip can be soldered into the small holes on the logic connection side of the board to enable use with solderless breadboards, perfboards, or 0.1″ connectors. For the most compact installation, you can just solder wires directly to the holes.

Key features of the SMC G2 family

  • Simple bidirectional control of one brushed DC motor
  • Five communication or control options:
    1. USB interface for direct connection to a PC
    2. Logic-level (TTL) serial interface for use with a microcontroller
    3. I²C interface for use with a microcontroller
    4. Hobby radio control (RC) pulse width interface for direct connection to an RC receiver or RC servo controller
    5. 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
  • Features of the serial, I²C, and USB interfaces:
    • Optional CRC error detection to eliminate communication errors caused by noise or software faults
    • Optional command timeout (shut off motors if communication ceases)
  • Serial features:
    • Controllable from a computer via serial commands sent to the device’s USB virtual serial (COM) port, or via TTL serial through the device’s RX/TX pins
    • TTL serial uses 0 V and 3.3 V on TX, accepts 0 V to 5 V on RX
    • 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
  • I²C features:
    • Compatible with I²C bus voltage levels from 1.8 V to 5 V
  • 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
    • 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
