About the XDuinoRail-Breakout-RailcomDetect

XDuinoRail-Breakout-RailcomDetect is an open source PCB design by chatelao, published on GitHub under the AGPL-3.0 license. It is a 2-layer board measuring 49.5 × 49.5 mm, with 47 components from 20 distinct parts.

Other key parts include the LM339 and 74HC02. By type, the board carries 23 resistors, 11 diodes, 4 transistors, 3 capacitors, 2 ICs and 1 connector.

It belongs with the dev boards & breakouts and iot & wireless designs in this gallery.

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.
