Questions
How big is the Lab-1-PCB PCB?
It measures 50.8 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab-1-PCB use?
36 parts, built around the MCP4921-E/P, LM317 and LT1009CD. 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-1-PCB KiCad files?
From the wesleywlho/EEC134ALab1PCB repository on GitHub, at the commit this page was made from: the board is Lab-1-PCB/Lab-1-PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab-1-PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask wesleywlho before reusing the design.
