Questions

How big is the PM3 Audio and DMX PCB?

It measures 121.9 × 66 mm and has 4 copper layers, 1.6 mm thick.

What parts does the PM3 Audio and DMX use?

194 parts, built around the CRE1S0505SC, ESP32-WROOM-32E, OPA2134UA and CS4271-CZZ. 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 PM3 Audio and DMX KiCad files?

From the Tommy270502/PM3 repository on GitHub, at the commit this page was made from: the board is 3_Technical_Documents/PCB/PM3_Audio_and_DMX_Template/PM3_Audio_and_DMX_Template/PM3_Audio_and_DMX.kicad_pcb and its schematic 3_Technical_Documents/PCB/PM3_Audio_and_DMX_Template/PM3_Audio_and_DMX_Template/DMX_out.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PM3 Audio and DMX design in my own project?

Its repository states no licence, so its author keeps all rights: ask Tommy270502 before reusing the design.
