Questions
How big is the Espamp PCB?
It measures 68.8 × 135.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Espamp use?
127 parts, built around the ESP32-S3-WROOM-1-N8, TAS5825MRHBR, TPS54202DDC and MPP684J2S1001. 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 Espamp KiCad files?
From the marmbrus/circuits repository on GitHub, at the commit this page was made from: the board is espamp/espamp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Espamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask marmbrus before reusing the design.
