Questions
How big is the HydroNode v01 PCB?
It measures 150 × 125 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HydroNode v01 use?
47 parts, built around the ESP32-WROOM-32D. 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 HydroNode v01 KiCad files?
From the donnahs/boardforge-ai repository on GitHub, at the commit this page was made from: the board is HydroNode-v01/kicad/HydroNode-v01.kicad_pcb and its schematic HydroNode-v01/kicad/HydroNode-v01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HydroNode v01 design in my own project?
Its repository states no licence, so its author keeps all rights: ask donnahs before reusing the design.
