Questions
How big is the Current PCB?
It measures 54.4 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Current use?
55 parts, built around the TLV9162ID, LMH6611MK, MIC5504-3.3YM5 and NLASB3157MT. 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 Current KiCad files?
From the ataradov/current repository on GitHub, at the commit this page was made from: the board is hw/current.kicad_pcb and its schematic hw/current.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current design in my own project?
Its repository states no licence, so its author keeps all rights: ask ataradov before reusing the design.
