Questions
How big is the SplitX decoder PCB?
It measures 31.5 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SplitX decoder use?
8 parts. 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 SplitX decoder KiCad files?
From the Open-Source-Model-Railway-Electronics/Wire-Splits repository on GitHub, at the commit this page was made from: the board is hardware/splitX_decoder/splitX_decoder.kicad_pcb and its schematic hardware/SplitX_1/SplitX_1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SplitX decoder design in my own project?
Its repository states no licence, so its author keeps all rights: ask Open-Source-Model-Railway-Electronics before reusing the design.
