We can split this out into separate repos later, right now its very convenient to have everything here.

Bouni/BSH-Board
A board that interfaces the DBUS of several home appliances and brings them into Home-Assitant via ESPHome

It measures 96 × 85 mm and has 2 copper layers, 1.6 mm thick.
59 parts, built around the STM32F103C8T6 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.
From the fdreshaj/PCB_DESIGN_WORKSHOP_STM32 repository on GitHub, at the commit this page was made from: the board is STM32_PCB_Workshop_Design/STM32_PCB_Workshop_Design.kicad_pcb and its schematic STM32_PCB_Workshop_Design/STM32_PCB_Workshop_Design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask fdreshaj before reusing the design.
