Questions
How big is the Stm32-io extend PCB?
It measures 68 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32-io extend use?
44 parts, built around the STM32F103C8T6, AMS1117-3.3, 1N5817WS and KMR241GLFS. 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 Stm32-io extend KiCad files?
From the hardenedlinux/cheap-pcb repository on GitHub, at the commit this page was made from: the board is stm32-io-extend/v6/stm32-io-extend.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32-io extend design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
