Questions
How big is the Ethnode PCB?
It measures 74 × 37 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ethnode use?
83 parts, built around the ESP32-WROVER-E(4MB), RTL8201FI-VC-CG, TPS5430DDA and 1N5819WS. 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 Ethnode KiCad files?
From the cr1tbit/ethnode repository on GitHub, at the commit this page was made from: the board is ethnode.kicad_pcb and its schematic ethnode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ethnode design in my own project?
Its repository states no licence, so its author keeps all rights: ask cr1tbit before reusing the design.
