Questions
How big is the AIR32CBT6 PCB?
It measures 21 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AIR32CBT6 use?
74 parts, built around the SGM2019-3.3YN5G/TR and BDFN2C051V. 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 AIR32CBT6 KiCad files?
From the pengwon/air32f103-mini repository on GitHub, at the commit this page was made from: the board is ref/Air32F103-Board/AIR32CBT6.kicad_pcb and its schematic ref/Air32F103-Board/AIR32CBT6.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AIR32CBT6 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
