Questions
How big is the Utcs isource PCB?
It measures 101.6 × 101.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Utcs isource use?
40 parts, built around the AD8221AR and OP1177AR. 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 Utcs isource KiCad files?
From the akshmakov/utcs-isource repository on GitHub, at the commit this page was made from: the board is kicad/utcs-isource.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Utcs isource design in my own project?
Its repository states no licence, so its author keeps all rights: ask akshmakov before reusing the design.
