Features
The hardware revision 2 contains new features like a larger buzzer with hardware controllable volume courtousy of a PAM8904. Additionally, the faceplate has been redesigned to operate on i2c communication to be removable with just a single 5 pin JST connection. Being based on the ESP32 feather V2 by adafruit, bluetooth and wifi features will be added eventually. Build guide and BOM to come after prototyping hardware V2 is more solidified.

Questions
How big is the LightPCB PCB?
It measures 59 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LightPCB use?
24 parts. 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 LightPCB KiCad files?
From the bkp0515/Buzzer-Box repository on GitHub, at the commit this page was made from: the board is lightPCB/lightPCB.kicad_pcb and its schematic jackPCB/jackPCB/jackPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LightPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask bkp0515 before reusing the design.
