Questions
How big is the Current source PCB?
It measures 80 × 24.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Current source use?
28 parts, built around the 78L08 and 1.5KE7.5A. 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 source KiCad files?
From the dzavalishin/hardware repository on GitHub, at the commit this page was made from: the board is _Sensors/current_source/current_source.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current source design in my own project?
Its repository states no licence, so its author keeps all rights: ask dzavalishin before reusing the design.
