Questions
What parts does the Modulo I2C use?
27 parts, built around the PCF8574T and IRF540N. 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 Modulo I2C KiCad files?
From the flukedf/PCB-Cards repository on GitHub, at the commit this page was made from: the board is Modulo_I2C/Modulo_I2C.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Modulo I2C design in my own project?
Its repository states no licence, so its author keeps all rights: ask flukedf before reusing the design.
