Questions
What parts does the STM32 Bluetooth Hardware Design use?
42 parts, built around the DLF162500LT-5028A1, USBLC6-2SC6 and MIC5365-3.3YD5-TR. 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 Hardware Design KiCad files?
From the mfrisch3/BluetoothMicroPCB repository on GitHub, at the commit this page was made from: the board is STM32 Bluetooth Hardware Design.kicad_pcb and its schematic MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 Bluetooth Hardware Design design in my own project?
Its repository states no licence, so its author keeps all rights: ask mfrisch3 before reusing the design.
