Questions
How big is the Solar Tracer PCB?
It measures 40 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Solar Tracer use?
58 parts, built around the ESP32-S3-WROOM-1-N8, AT8236, QMC5883L and TX4137. 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 Solar Tracer KiCad files?
From the TDA-2030/Solar-Tracer repository on GitHub, at the commit this page was made from: the board is hardware/solar_tracer.kicad_pcb and its schematic hardware/Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Solar Tracer design in my own project?
Its repository states no licence, so its author keeps all rights: ask TDA-2030 before reusing the design.
