Questions
How big is the Trace PCB?
It measures 45.4 × 22.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trace use?
15 parts, built around the ESP32-S3-WROOM-1-N8, AMS1117-3.3, TCJB226M025R0150E and CC0805KRX7R9BB104. 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 Trace KiCad files?
From the ayaangrover/trace repository on GitHub, at the commit this page was made from: the board is trace/trace.kicad_pcb and its schematic trace/trace.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trace design in my own project?
Its repository states no licence, so its author keeps all rights: ask ayaangrover before reusing the design.
