Questions
How big is the NewMXtest PCB?
It measures 380 × 128 mm and has 4 copper layers, 1.6 mm thick.
What parts does the NewMXtest use?
339 parts, built around the 74LVC1T45W6, PRTR5V0U2X and SK6812-EC20. 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 NewMXtest KiCad files?
From the phpbbireland/echo repository on GitHub, at the commit this page was made from: the board is iso_encoder/Echo_Ayla_Final/NewMXtest.kicad_pcb and its schematic 34 Pin Extender Board/adapter64.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NewMXtest design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
