Questions
How big is the CatLickDet PCB?
It measures 42.8 × 42.2 mm and has 4 copper layers, 1.61 mm thick.
What parts does the CatLickDet use?
78 parts, built around the LM27761DSG and LT3045EDD. 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 CatLickDet KiCad files?
From the Nick-Lemberger/3DqsOBM repository on GitHub, at the commit this page was made from: the board is 4Q-Epi Detector/CatLickDet.kicad_pcb and its schematic 4Q-Epi Detector/CatLickDet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CatLickDet 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).
