Questions
How big is the THM32Hardware PCB?
It measures 71.8 × 35.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the THM32Hardware use?
10 parts, built around the ESP32-WROOM-32 and AMS1117-3.3. 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 THM32Hardware KiCad files?
From the eldanb/THM32 repository on GitHub, at the commit this page was made from: the board is THM32Hardware/THM32Hardware.kicad_pcb and its schematic THM32Hardware/THM32Hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the THM32Hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask eldanb before reusing the design.
