Questions
How big is the PI DMX hat PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PI DMX hat use?
53 parts, built around the ISO3088DW, TPS5430DDA, CAT24C256LI and SS54. 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 PI DMX hat KiCad files?
From the Skrooter/PI-DMX-hat repository on GitHub, at the commit this page was made from: the board is pcb/pi-dmx-hat.kicad_pcb and its schematic pcb/MIDI-DMX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PI DMX hat design in my own project?
Its repository states no licence, so its author keeps all rights: ask Skrooter before reusing the design.
