About the XDuinoRail-Protoboard PCB

XDuinoRail-Protoboard is an open source AVR/Arduino PCB design by chatelao, published on GitHub under the AGPL-3.0 license. It is a 2-layer board measuring 100 × 100 mm, with 42 components from 21 distinct parts.

Its main chip is the Arduino_UNO_R3, from the AVR/Arduino family. Other key parts include the ULN2003, AMS1117-3.3, LIS3DH, L78L05_SOT89 and TPS5430DDA. By type, the board carries 14 connectors, 10 transistors, 7 ICs, 5 jumpers, 4 diodes and 1 module.

It belongs with the 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.

XDuinoRail-Protoboard: common questions

What microcontroller does the XDuinoRail-Protoboard use?

The XDuinoRail-Protoboard is built around the Arduino_UNO_R3, from the AVR/Arduino family.

How big is the XDuinoRail-Protoboard PCB?

The XDuinoRail-Protoboard measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the XDuinoRail-Protoboard?

42 components, from 21 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-Protoboard 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-Protoboard 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-Protoboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
