Questions
How big is the MCP2221A Board PCB?
It measures 50.8 × 19 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MCP2221A Board use?
22 parts, built around the PGB1010603NR. 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 MCP2221A Board KiCad files?
From the MaLoSW/MCP2221A-Dev-Board repository on GitHub, at the commit this page was made from: the board is MCP2221A_Board.kicad_pcb and its schematic MCP2221A_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MCP2221A Board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
