Questions
How big is the ATP PCB?
It measures 49.4 × 49.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ATP use?
75 parts, built around the ESP32-C3-WROOM-02-H4, LM386, XC6220B331MR-G and ESD9B5.0ST5G. 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 ATP KiCad files?
From the hito-ren/ESP-Audio-Processor repository on GitHub, at the commit this page was made from: the board is Schematic & PCB/ATP.kicad_pcb and its schematic Schematic & PCB/ATP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ATP design in my own project?
Its repository states no licence, so its author keeps all rights: ask hito-ren before reusing the design.
