Questions
How big is the Bluetooth PCB?
It measures 40.4 × 25.8 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Bluetooth use?
44 parts, built around the DLF162500LT-5028A1, TLV75533PDBVR-MS, BAT54J and ESDA5V3L. 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 Bluetooth KiCad files?
From the takay03/bluetooth-pcb repository on GitHub, at the commit this page was made from: the board is bluetooth.kicad_pcb and its schematic bluetooth.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bluetooth design in my own project?
Its repository states no licence, so its author keeps all rights: ask takay03 before reusing the design.
