Questions

How big is the I2CADC01 PCB?

It measures 30 × 40.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the I2CADC01 use?

33 parts, built around the BAT46. 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 I2CADC01 KiCad files?

From the mlab-modules/I2CADC01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/I2CADC01.kicad_pcb and its schematic hw/sch_pcb/I2CADC01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the I2CADC01 design in my own project?

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