Questions
How big is the USB UART MicroUSB PCB?
It measures 33 × 24.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB UART MicroUSB use?
27 parts, built around the CP2102N-A01-GQFN28R, MMBT2222A and SP0503BAHTG. 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 USB UART MicroUSB KiCad files?
From the vintlabs/USB-UART-MicroUSB repository on GitHub, at the commit this page was made from: the board is USB-UART-MicroUSB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB UART MicroUSB 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).
