Questions
How big is the CurrentSink PCB?
It measures 34 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CurrentSink use?
42 parts, built around the LMV358, MCP1640T-I/MC, MCP4802-E/SN and LM2931CD. 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 CurrentSink KiCad files?
From the plainsimpledot/currentSink repository on GitHub, at the commit this page was made from: the board is currentSink.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CurrentSink design in my own project?
Its repository states no licence, so its author keeps all rights: ask plainsimpledot before reusing the design.
