Overview

ArduinoDCC++ is an open-source printed circuit board by danielvilas, from the danielvilas/DigitalTrains repository on GitHub, published under the MIT licence. It is a 2-layer board of 100 × 88 mm with 79 parts on 69 nets, routed with 672 tracks and 98 vias.

It is built around the ATMEGA328PB-AU, LMV358 and FT231XS-R, with the L298P, SS14 and 1N4148WS among its other parts. Its parts include 21 resistors, 17 capacitors, 16 diodes, 9 connectors and 5 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Digital Trains is a repository for storing and sharing my DCC/LCC setups

Up to Date this contians Circuits, boards and projects usefull for my model layout. Each folder is a project I started. some are finished, others are Work In Progress

Folder	Description	Status¹
ArduinoDCC++	Board for use whit DCC++	Deprecated for DccBlocks
Breaker	DC breaker board, shorts protections	Frozen, no need on DCC²
dcc-turnout	Board to control a turnout with servo	Alive - prototype phase
dcc-turnout-config	Tool to configure the dcc-turnout boards	Alive - conceptual design
DccBlocks	Components to create a DCC system whit DCC++. Has subprojects	Stall - currently works, needs update to DCC++EX
docs	Different documents may be usefull	Alive - Slow
Esp32Lcc	Use an ESP32 as node for LCC	Stall - Reading about

Versioning

First projects uses a folder per version system, easy to follow, easy to view older versions, but mess the file system.

Current system based on tags, and the creation of doc directories with PDFs of the schematic and the layers.

Questions

How big is the ArduinoDCC++ PCB?

It measures 100 × 88 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ArduinoDCC++ use?

79 parts, built around the ATMEGA328PB-AU, LMV358, FT231XS-R and L298P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the ArduinoDCC++ KiCad files?

From the danielvilas/DigitalTrains repository on GitHub, at the commit this page was made from: the board is ArduinoDCC++/0.0.1-j/ArduinoDCC++.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ArduinoDCC++ design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
