Questions
How big is the MBusCH55x PCB?
It measures 32.9 × 49.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MBusCH55x use?
50 parts, built around the CH552E and CH552G. 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 MBusCH55x KiCad files?
From the jmysu/mBusCH55x repository on GitHub, at the commit this page was made from: the board is hardware/mBusCH55x.KiCAD8/mBusCH55x.kicad_pcb and its schematic hardware/mBusCH55x.KiCAD8/mBusCH55x.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MBusCH55x 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).
