SKU: DCCSC2.A4988.Assembled.Uno Category: Tags: , , , , ,


A fully assembled shield to enable an Arduino Uno with a A4988 controller to become a Model Railway DCC Turntable Accessory Decoder – control your turntable from your DCC Command Station.

Use this interface with an Arduino Uno and a A4988 controller to create your own DCC turntable Accessory Decoder.

No more messing about with breadboards / multiple power adapters.

This board features

  • header pins / holes for 12v DC power connector, supplying power to the Stepper Motor, A4988 controller AND Arduino (5v DC )
  • header pins / holes for an Arduino UNO( R3 )
  • header pins / holes for an A4988 stepper motor controller
  • header pins / holes for a simple sensor ( GND, 5V, I/O connected to D3 on the Arduino )
  • header pins / holes for the DCC Input from the track.
  • jumper pin to allow the Arduino Uno to be powered by the DCC Shield.

This is a complete assembled kit with all the components required, including the A4988 but without the Arduino Uno . Click here to purchase an Arduino Uno.

The assembled product contains the following components

  • Screw Terminals ( 4 x 2 pin, 1 x 3 pin )
  • Header pins ( for Arduino and Stepper Controller )
  • 3 Capacitors
  • 7805 12v DC to 5v DC convertor ( Heat sink not provided but must be used )
  • 1 Diode
  • 3 Resistors
  • 1 high speed optocoupler ( 6N137 )
  • A4988 stepper motor controller

The board will be fully assembled and tested ( using an in-house Arduino ) with the example sketch on the How To Page.
