This project is one of many variants of a PCB that can be used to interface with B/S/H appliances using the awsome bsh-home-appliances project.
Warning
[!WARNING] Household appliances work with high voltages and currents. They generate heat and steam, they shake, vibrate and have rotating parts. You should have a good knowledge of electrics and take appropriate safety measures before opening or modifying such an appliance. Parts can get wet or hot, move or fall off.
[!WARNING] Even if parts of the appliances operate at low voltages, depending on your specific model they may or may not be isolated from earth. This is a good chance of death or serious injury. I'm not responsible if you kill your cat, your spouse, your favourite pet fish, or yourself, whichever of these is the worst for you. You have been warned.

Questions
How big is the BSH Board PCB?
It measures 24 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BSH Board use?
75 parts, built around the 74LVC1G07, 74LVC1G17Z, ESP32-C6-MINI-1-N4 and AP63203WU. 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 BSH Board KiCad files?
From the Bouni/BSH-Board repository on GitHub, at the commit this page was made from: the board is BSH-Board.kicad_pcb and its schematic BSH-Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BSH Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask Bouni before reusing the design.
