Questions
How big is the Scalenode cm4-baseboard PCB?
It measures 128.5 × 40 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Scalenode cm4-baseboard use?
146 parts, built around the PDQE30-Q48-S5-D, TPS2378DDA, URB4805YMD-30WR3 and FT234XD-R. 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 Scalenode cm4-baseboard KiCad files?
From the antmicro/scalenode-cm4-baseboard repository on GitHub, at the commit this page was made from: the board is scalenode-cm4-baseboard.kicad_pcb and its schematic compute-module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scalenode cm4-baseboard design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
