Questions
How big is the First test PCB?
It measures 39 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the First test use?
17 parts, built around the AMS1117-3.3. 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 First test KiCad files?
From the ABigBright/stm32_schematic repository on GitHub, at the commit this page was made from: the board is first_test.kicad_pcb and its schematic first_test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the First test design in my own project?
Its repository states no licence, so its author keeps all rights: ask ABigBright before reusing the design.
