From the project

The friendly decoder development plattform for model railroad tinkers.

The friendly decoder development plattform for model railroad tinkers.

The primary tinker formfactor is the "Arduino UNO R3":

The XIAO formfactor may even fit some H0 locomotives, so COMING SOON:

Data - It extracts DCC raw signals from the rails. - It provides raw (RailCom) feedback to the rails.

The data pins are X (input) and Y (output) per default (no soldering needed, but can be reassigned to any other GPIO-Pins.
