Questions
How big is the Backplane PCB?
It measures 186.7 × 99.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Backplane use?
43 parts, built around the CP2102-GMR and DS1813-5+. 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 Backplane KiCad files?
From the lenzjo/MECB-Backplane repository on GitHub, at the commit this page was made from: the board is backplane.kicad_pcb and its schematic backplane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Backplane design in my own project?
Its repository states no licence, so its author keeps all rights: ask lenzjo before reusing the design.
