Questions

How big is the EE120Blab1 PCB?

It measures 79 × 86.9 mm and has 2 copper layers, 1.6 mm thick.

What parts does the EE120Blab1 use?

13 parts. 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 EE120Blab1 KiCad files?

From the PugsinCoding/PCB_Practice repository on GitHub, at the commit this page was made from: the board is EE120B_Lab1/KiCad/EE120Blab1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the EE120Blab1 design in my own project?

Its repository states no licence, so its author keeps all rights: ask PugsinCoding before reusing the design.
