Questions
How big is the Sensorinterface PCB?
It measures 31.5 × 20.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensorinterface use?
20 parts, built around the LM393. 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 Sensorinterface KiCad files?
From the bullestock/alphaclock repository on GitHub, at the commit this page was made from: the board is pcb/sensorinterface/sensorinterface.kicad_pcb and its schematic pcb/sensorinterface/sensorinterface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensorinterface design in my own project?
Its repository states no licence, so its author keeps all rights: ask bullestock before reusing the design.
