Questions
What parts does the Beehive use?
40 parts, built around the ESP32-S3-WROOM-1U-N4, BME280, HX711 and MP2307DN-Z. 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 Beehive KiCad files?
From the waterclear1/BeehiveMonitor_Hardware repository on GitHub, at the commit this page was made from: the board is beehive/beehive.kicad_pcb and its schematic beehive/beehive.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beehive design in my own project?
Its repository states no licence, so its author keeps all rights: ask waterclear1 before reusing the design.
