Questions
How big is the STM32Inverter PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32Inverter use?
154 parts, built around the MCP2551-I/SN-HG, LM358, 74HCT08D and LM393. 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 STM32Inverter KiCad files?
From the Zychlix/Inverter32 repository on GitHub, at the commit this page was made from: the board is STM32Inverter.kicad_pcb and its schematic STM32Inverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32Inverter design in my own project?
Its repository states no licence, so its author keeps all rights: ask Zychlix before reusing the design.
