Questions
How big is the Green net PCB?
It measures 84.8 × 67 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Green net use?
82 parts, built around the ESP32-S3-WROOM-1-N4R2, AP63203WU, BME280 and CP2102N-A02-GQFN28. 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 Green net KiCad files?
From the benjisu03/green-net repository on GitHub, at the commit this page was made from: the board is GreenNet/GreenNet.kicad_pcb and its schematic GreenNet/GreenNet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Green net design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
