Questions
How big is the I2C Scanner PCB?
It measures 63 × 33.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the I2C Scanner use?
61 parts, built around the RP2040, W25Q128JVSIQ, TXS0108EPW and ABM8-272-T3. 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 I2C Scanner KiCad files?
From the VCoccoli/RPS_PCB repository on GitHub, at the commit this page was made from: the board is I2C_Scanner/I2C_Scanner.kicad_pcb and its schematic I2C_Scanner/I2C_Scanner.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the I2C Scanner design in my own project?
Its repository states no licence, so its author keeps all rights: ask VCoccoli before reusing the design.
