Questions
How big is the Z input PCB?
It measures 60.7 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Z input use?
19 parts, built around the OPB616 and BCP5616QTA. 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 Z input KiCad files?
From the Secoh/Electronics repository on GitHub, at the commit this page was made from: the board is RuggedLogic/24V_Z_vs_Rail_to_MCU_digital_input/kicad/z-input/z-input.kicad_pcb and its schematic MCU/D11/starter_d11/starter_d11.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Z input design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
