Questions
How big is the Rpi industrial analog PCB?
It measures 88.4 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rpi industrial analog use?
76 parts, built around the AD8220ARM, MCP3424-E/SL and SMBJ20CA. 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 Rpi industrial analog KiCad files?
From the davisjp1822/Analog_Persistence repository on GitHub, at the commit this page was made from: the board is rpi-industrial-analog.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rpi industrial analog 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).
