Questions
How big is the RFIQINT02B PCB?
It measures 40.1 × 60.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RFIQINT02B use?
46 parts, built around the SI53322-B-GM, 4.7UF 16V and BLM21PG331SN1D. 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 RFIQINT02B KiCad files?
From the mlab-modules/RFIQINT02 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/RFIQINT02B.kicad_pcb and its schematic hw/sch_pcb/RFIQINT02B.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RFIQINT02B design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
