Questions
How big is the OpticalAbsorptionMeasurement PCB?
It measures 160 × 160 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpticalAbsorptionMeasurement use?
171 parts, built around the OPA602AU, L7812, L7912 and J111. 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 OpticalAbsorptionMeasurement KiCad files?
From the Johann-Schmid/opticalAbsorptionMeasurement repository on GitHub, at the commit this page was made from: the board is opticalAbsorptionMeasurement.kicad_pcb and its schematic opticalAbsorptionMeasurement.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpticalAbsorptionMeasurement design in my own project?
Its repository states no licence, so its author keeps all rights: ask Johann-Schmid before reusing the design.
