Questions
What parts does the HomeAssitantESP32Node use?
34 parts, built around the ESP32-WROOM-32UE-N4, R-78E5.0-0.5, AP2112K-3.3 and PCA9615DP. 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 HomeAssitantESP32Node KiCad files?
From the JoelEB/ESP_Smart_Home repository on GitHub, at the commit this page was made from: the board is HomeAssitantESP32Node/HomeAssitantESP32Node.kicad_pcb and its schematic HomeAssitantESP32Node/HomeAssitantESP32Node.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HomeAssitantESP32Node design in my own project?
Its repository states no licence, so its author keeps all rights: ask JoelEB before reusing the design.
