Questions

How big is the Lab3 PCB?

It measures 25.5 × 19 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Lab3 use?

16 parts, built around the APDS-9960 and MIC5376-2.8YC5-TR. 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 Lab3 KiCad files?

From the Dom-Taing/lab repository on GitHub, at the commit this page was made from: the board is Lab3/Lab3.kicad_pcb and its schematic Lab3/Lab3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lab3 design in my own project?

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