This is a Bluepill-compatible devboard for the STM32F103C8T6 microcontroller. It uses 0805 surface mount parts and a few through hole parts that can be easily obtained as generic components. It is intended to be an alternative should the should the Bluepill not be available, especially given the number of fake parts that have appeared lately. The layout 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 STM32surface PCB?
It measures 23 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32surface use?
25 parts, built around the STM32F103C8T6. 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 STM32surface KiCad files?
From the profdc9/STM32surface repository on GitHub, at the commit this page was made from: the board is STM32surface.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32surface design in my own project?
Its repository states no licence, so its author keeps all rights: ask profdc9 before reusing the design.
