SKU: DCCI-Nano-Shield-1 Category: Tags: , , , ,


A small and simple Shield to enable an Arduino Nano v3 to become a Model Railway DCC Accessory Decoder.

Use this interface with an Arduino Nano v3 ( not supplied, but obtained here ) to create your own Accessory Decoders, DCC monitors, turn out control, signal control in fact anything your imagination can create.

No more messing about with breadboards. A strip of connectors on each side of the Nano socket allows you to connect your own accessories, such as LED’s or interface with the I2C Bus.


Board Connections….

The 2 pin connector is the DCC input. Your DCC feed will be two wires – one to each rail – connect a feed from one rail to Pin 1, and another feed from the other rail to Pin 2.

The Arduino is powered from the DCC Bus and also provides a connector for an ACK circuit ( coming soon )

Testing the Interface.

The easiest way to test the interface is to upload a monitoring sketch from MynaBay Inc. and watch the packets appear on the Serial Monitor in the Arduino IDE.

Follow the instructions from Step 15 to install the DCC_Decoder library.

Take a look at an example sketch to see how it can be turned in to a small cheap DCC decoder…
