Questions
How big is the Cm4-carrier net PCB?
It measures 90 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cm4-carrier net use?
45 parts, built around the TPD2EUSB30DRT and DMP2066LSN. 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 Cm4-carrier net KiCad files?
From the jkiv/cm4-carriers repository on GitHub, at the commit this page was made from: the board is hardware/cm4-carrier-net/cm4-carrier-net.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cm4-carrier net design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
