Questions
How big is the Lab 7 PCB?
It measures 75 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab 7 use?
45 parts, built around the TLV2372IP, TPS2832D and CSD18534KCS. 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 Lab 7 KiCad files?
From the jpt1729/ECE302_Lab7 repository on GitHub, at the commit this page was made from: the board is Lab 7.kicad_pcb and its schematic Lab 7.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab 7 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jpt1729 before reusing the design.
