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.

XDuinoRail-Debug: common questions
What microcontroller does the XDuinoRail-Debug use?
The XDuinoRail-Debug is built around the RP2040, from the RP2040/RP2350 family.
How big is the XDuinoRail-Debug PCB?
The XDuinoRail-Debug measures 99.1 × 99 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the XDuinoRail-Debug?
147 components, from 63 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the XDuinoRail-Debug design files?
From the chatelao/xDuinoRail-Decoder repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the XDuinoRail-Debug design in my own project?
Yes, under the terms of its AGPL-3.0 license, which chatelao chose for the repository.
Can I test firmware for the XDuinoRail-Debug without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
