Questions
How big is the Stm32f030 adc PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32f030 adc use?
46 parts, built around the AMS1117-3.3 and BC337. 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 Stm32f030 adc KiCad files?
From the USBBAD/awful-hardware repository on GitHub, at the commit this page was made from: the board is stm32f030_adc/stm32f030_adc.kicad_pcb and its schematic simulations/bjt-amp-simulation/bjt-amp-simulation.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32f030 adc design in my own project?
Its repository states no licence, so its author keeps all rights: ask USBBAD before reusing the design.
