Questions
How big is the Silence PCB?
It measures 68 × 68 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Silence use?
149 parts, built around the TLV9001IDCK, ESP32-WROOM-32, MMBT5551L and GZ1608D601TF. 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 Silence KiCad files?
From the atx/silence repository on GitHub, at the commit this page was made from: the board is silence.kicad_pcb and its schematic current_sense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Silence design in my own project?
Its repository publishes it under the CC0-1.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
