Latest DCC++ EX Official Release


17 Feb 2022: DCC++EX 4.0 is released! This now includes EX-RAIL & HAL, plus much more…


On the releases page, select the most recent version and download the .zip file. You will see the 2 files for download, choose the compression format you prefer: or CommandStation-EX.tar.gz. The zip/tar file contains the Arduino Sketch file for DCC++ EX. You will need either the Arduino IDE or the PlatformIO development environment in order to upload it to your microcontroller board. Click here for Arduino IDE installation instructions.

Latest DCC++ EX Unreleased Development Version


The link below will download the latest unreleased development version in zip file format. Please open the zip file, go into the “CommandStation-EX-master” folder, and unzip all the files in that folder into your “CommandStation-EX” sketch folder. Make sure you DO NOT just unzip the entire zip file, since it will have the incorrect folder name. The Arduino IDE requires that the folder name and the .ino file inside that folder match names exactly, i.e.: “CommandStation-EX” not “CommandStation-EX-master”.


Discord is the best place to keep up-to-date on new code releases, and you may be directed to download the latest version here from time to time, as new features are added and updated often.

CommandStation-EX Repository (project source files)


The link below will take you the the CommandStation-EX GitHub repository, where you can clone the project to your computer. Click on the green button to get a clone link or to download the zip file. We have made sure that you can still use the Arduino IDE if you like, but we recommend developers use the PlatformIO development environment. See the Contributing Page for more information.

Getting BaseStation-Classic

The installer will allow you to install BaseStation-Classic. We recommend using the newer CommandStation-EX. If you are looking for the original source for the project (with some minor bug fixes and improvements), see the links below.


This version is not actively maintained, and will only be updated with bug fixes.
