The repository for DCC Hardware projects
The DCC project is an attempt to implement a DCC (Digital Command Control) Command Station based on the BeagleBone Black platform. The project consists of four parts:
- DCC_BBB : the Linux code for the BeagleBone.
- DCC_PRU : the PRU code for generating the actuel DCC signal (including RailCom cutout).
- DCC_AVR : the AVR code for additional interfaces (for example Expressnet).
- DCC_Hardware (this repo) : the schematics and PCB-layout files for the hardware (KiCad)

Questions
How big is the DCC V2 PCB?
It measures 160 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DCC V2 use?
101 parts, built around the ATMEGA1284-PU, MAX485ED, L6203 and 74HC123D. 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 DCC V2 KiCad files?
From the PaulVdBergh/DCC_Hardware repository on GitHub, at the commit this page was made from: the board is DCC_Booster/DCC_V2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCC V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask PaulVdBergh before reusing the design.
