Questions
How big is the STM32 bluetooth PCB?
It measures 50.8 × 26 mm and has 4 copper layers, 1.58 mm thick.
What parts does the STM32 bluetooth use?
48 parts, built around the STM32WB55CEU6, DLF162500LT-5028A1, MIC5365-3.3YD5-TR and USBLC6-2SC6. 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 bluetooth KiCad files?
From the hello-world2461/STM32_bluetooth repository on GitHub, at the commit this page was made from: the board is STM32_bluetooth.kicad_pcb and its schematic STM32_bluetooth.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 bluetooth design in my own project?
Its repository states no licence, so its author keeps all rights: ask hello-world2461 before reusing the design.
