Questions
How big is the I2CMultiplexer PCB?
It measures 101.6 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the I2CMultiplexer use?
110 parts, built around the PCF8574TS/3 and MAX40200AUK. 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 I2CMultiplexer KiCad files?
From the freudenthal/I2CTCA9548Multiplexer repository on GitHub, at the commit this page was made from: the board is I2CMultiplexer.kicad_pcb and its schematic DigitalIO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the I2CMultiplexer design in my own project?
Its repository states no licence, so its author keeps all rights: ask freudenthal before reusing the design.
