Questions
How big is the DCCShield PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DCCShield use?
17 parts, built around the LMD18200T. 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 DCCShield KiCad files?
From the RobertPHeller/RPi-RRCircuits repository on GitHub, at the commit this page was made from: the board is DCCShield/DCCShield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DCCShield design in my own project?
Its repository states no licence, so its author keeps all rights: ask RobertPHeller before reusing the design.
