Questions
How big is the Switched current source PCB?
It measures 83 × 47 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Switched current source use?
64 parts, built around the LM358, MMBT3904 and MMBT3906. 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 Switched current source KiCad files?
From the CoolNamesAllTaken/ee308 repository on GitHub, at the commit this page was made from: the board is lab3/switched_current_source/switched_current_source.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switched current source design in my own project?
Its repository states no licence, so its author keeps all rights: ask CoolNamesAllTaken before reusing the design.
