Questions

How big is the ProMicro UART PCB?

It measures 17.8 × 33 mm and has 2 copper layers, 1 mm thick.

What parts does the ProMicro UART use?

56 parts, built around the FT232H. 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 ProMicro UART KiCad files?

From the clayton13/ProMicro repository on GitHub, at the commit this page was made from: the board is UART/ProMicro_UART.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ProMicro UART design in my own project?

Its repository states no licence, so its author keeps all rights: ask clayton13 before reusing the design.
