Questions
How big is the Dmxboard PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dmxboard use?
39 parts, built around the THVD1420DRL, SFH11-PBPC-D07-RA-BK, SBH11-PBPC-D07-RA-BK and PBH2UEESNPNAGX. 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 Dmxboard KiCad files?
From the tobiashellbusch/dmx-pcb repository on GitHub, at the commit this page was made from: the board is dmxboard.kicad_pcb and its schematic dmxboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dmxboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask tobiashellbusch before reusing the design.
