Questions
How big is the TRACER PCB?
It measures 99.6 × 69.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TRACER use?
82 parts, built around the ESP32-S3-WROOM-1-N8 and AP2112K-3.3. 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 TRACER KiCad files?
From the CoderN-P/TRACER-PCB repository on GitHub, at the commit this page was made from: the board is TRACER.kicad_pcb and its schematic TRACER.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TRACER design in my own project?
Its repository states no licence, so its author keeps all rights: ask CoderN-P before reusing the design.
