AR-SD4DXDU-D-NC 10 Pack

Please note: The image shows the AR-SD4DXEU-T version of the board with the screw terminal connectors installed.

The AR-SD4DX series of boards are complete step-and-direction controllers for operating up to four step-and-direction stepper motor driver boards using a USB interface. They provide the capability of independently driving one to four stepper motors using external driver boards, such as those created by Applied Motion and Gecko. Since they have on-board high current drivers, they are capable of directly driving those external boards without external buffers.

Please note that the image shown is that of the AR-SD4DXEU-T. 

This variant (the AR-SD4DXDU-D-NC 10 pack) consists of ten of the AR-SD4DXDU-D-NC boards.  These units have two 0-5 volt DAC outputs available on the V0 and V1 pins, and use SIP headers facing down for all of the common I/O connectors except the USB connector.  It is also set up to use your own shipping account with UPS as a ground shipment.

PLEASE NOTE: The image shown is for the AR-SD4DXEU-T version of the SD4DX series, with screw terminal connectors installed.  The AR-SD4DXDU-D product replaces the screw-terminal connectors with downward-facing SIP headers and adds components to support the DAC outputs.

The board has ESD protection on most of the TTL inputs (except for the RST line).  Note that the protection is only active when the board is connected to a properly grounded power supply, such that the GND connection on the board power connector goes to true earth ground.

If your signal sources for the TTL inputs need to be optically isolated (such as signals whose voltage range is in the range of 5 to 24 volts), you may elect to use our AR-OPTOISO4CHAN product to act as an input buffer.

The firmware that is used describes the "personality" of the board.  You can reprogram the board with either of these firmwares at any time using the supplied firmware update tool.  If you like, you may use the cart comments field to request a particular firmware (remember: the SD4DXNCRouter firmware is installed by default, so you only need to do this if you would prefer the SD4DXPotRouter firmware to be preinstalled on your board.)

  • SD4DXPotRouter (click to see the manual) allows for simultaneous independent asynchronous motion between the motors.  This is normally the firmware preprogrammed onto  the board at the time of your order.
  • SD4DXNCRouter (click to see the manual) allows for pen-plotter-like control, wherein perfect rate scaling is automatically performed between the motors in order to generate the equivalent of straight-line motion if a pen plotter were to be attached.
