Questions
How big is the MHCI DMX PCB?
It measures 79 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MHCI DMX use?
89 parts, built around the TEC 2-1210WI, TJA1051T/3/1, TSR 2-2450 and SRV05-4. 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 MHCI DMX KiCad files?
From the About-Time-Technologies/MHCI repository on GitHub, at the commit this page was made from: the board is DMX/MHCI-DMX/MHCI-DMX.kicad_pcb and its schematic DMX/MHCI-DMX/MHCI-DMX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MHCI DMX design in my own project?
Its repository states no licence, so its author keeps all rights: ask About-Time-Technologies before reusing the design.
