Project Description
Minimal STM32 F4 Breakoutboard with USB-C and 10-pin SWD port.
STM32 NUCLEO boards do not have 10-pin SWD port and you are stuck with the provided ST-Link interface. I like using the BlackMagic GDB probe for development. https://github.com/blacksphere/blackmagic Checkout their amesome embeddded GDB server.
I think all projects should be using USB-C. I'm still running it in USB 2.0 mode. But the USB-C connector is the one to go with. ST application note for moving legacy USB 2.0 to USB C (AN4775) https://www.st.com/content/ccc/resource/technical/document/application_note/group0/a6/91/45/9e/12/a0/4d/42/DM00235987/files/DM00235987.pdf/jcr:content/translations/en.DM00235987.pdf

Questions
How big is the PurplePill PCB?
It measures 27.9 × 63.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PurplePill use?
32 parts. 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 PurplePill KiCad files?
From the jboard146/PurplePill repository on GitHub, at the commit this page was made from: the board is purple_pill.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PurplePill design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
