Questions
How big is the LabnodeIO PCB?
It measures 54.4 × 71.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LabnodeIO use?
79 parts, built around the LM324 and PCF8574T. 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 LabnodeIO KiCad files?
From the das-labor/automatization4.0 repository on GitHub, at the commit this page was made from: the board is hardware/LabnodeIO-XL/LabnodeIO.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LabnodeIO design in my own project?
Its repository states no licence, so its author keeps all rights: ask das-labor before reusing the design.
