Questions
How big is the Stm32 PCB?
It measures 100.1 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32 use?
59 parts, built around the STM32G070KBT6, BME280, DS18B20 and TPS61222DCK. 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 KiCad files?
From the jonatlib/stm32-433mhz repository on GitHub, at the commit this page was made from: the board is pcb/stm32/stm32.kicad_pcb and its schematic pcb/stm32/components_spi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonatlib before reusing the design.
