What is DCC-EX?
Article #45 - 13/01/2026 23:07DCC-EX is an open source (free) system that allows users to create DCC command stations using popular development boards such as some of the Arduino family.
After buying the development processor board and adding some extra hardware bits (power control shield) and downloading the free software, the base station can control DCC locomotives and accessories on a model railway layout.
Trains can then be controlled by free software on mobile phones/tablets/PCs or custom made throttle units.
