Questions
How big is the I2C232V01 PCB?
It measures 30 × 40.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the I2C232V01 use?
31 parts, built around the LE33CD-TR and SC18IM700IPW. 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 I2C232V01 KiCad files?
From the mlab-modules/I2C232V01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/I2C232V01.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the I2C232V01 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mlab-modules before reusing the design.
