Questions
How big is the Dmx PCB?
It measures 70 × 70 mm and has 4 copper layers, 1.62 mm thick.
What parts does the Dmx use?
63 parts, built around the THVD2442DRC, TLP2361(E, TPS78433QWDRBRQ1 and WS2812. 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 Dmx KiCad files?
From the versioduo/dmx repository on GitHub, at the commit this page was made from: the board is hardware/dmx.kicad_pcb and its schematic hardware/DMXLEDs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dmx design in my own project?
Its repository states no licence, so its author keeps all rights: ask versioduo before reusing the design.
