Description
The source code in this repository has any functions for TubeBox. TubeBox is conpact and simple vacuum tube amplifier. We created client application that works on Android and browser, server application that works on Raspbian on Raspberry Pi 3, and the DAC circuit that converts I2S to analog signal.

Questions
How big is the Sern PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sern use?
71 parts, built around the NE5534D, LT1028CP and PCM1794DB. 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 Sern KiCad files?
From the Heppokoyuki/sern repository on GitHub, at the commit this page was made from: the board is circuit/SERN.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sern design in my own project?
Its repository states no licence, so its author keeps all rights: ask Heppokoyuki before reusing the design.
