Questions
How big is the Bt controller PCB?
It measures 100 × 76 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bt controller use?
44 parts, built around the ESP32-DEVKITC-VE and 74HC595. 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 Bt controller KiCad files?
From the Chill-Sam/SpeakerSystem repository on GitHub, at the commit this page was made from: the board is hardware/pcb/bt_controller/bt_controller.kicad_pcb and its schematic hardware/pcb/bt_controller/bt_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bt controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Chill-Sam before reusing the design.
