README
README.mdThis is a Bluepill-compatible devboard for the STM32F103C8T6 microcontroller. It uses all through-hole parts except for the STM32F103C8T6/STM32F103CBT6 microcontroller and is intended to be an alternative to the Bluepill that is easier to assemble should the Bluepill not be available or suitable. It is somewhat optimized to be RFI resistant given it is a two-layer board This material is copyrighted by Daniel Marks (KW4TI) and licensed under the Creative Commons License CC-BY-SA 4.0.

Questions
How big is the STM32alt PCB?
It measures 26.7 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32alt use?
27 parts, built around the STM32F103C8T6 and LM1117-3.3. 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 STM32alt KiCad files?
From the profdc9/STM32alt repository on GitHub, at the commit this page was made from: the board is STM32alt.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32alt design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
