Questions
How big is the Temp sensor panel PCB?
It measures 188.7 × 147.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Temp sensor panel use?
961 parts, built around the ESP32-C3-MINI-1, BME280, SHTC3 and SI7020-A20-GM. 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 Temp sensor panel KiCad files?
From the juniper-garden/twig_temp_humidity_sensor repository on GitHub, at the commit this page was made from: the board is temp sensor_panel.kicad_pcb and its schematic temp sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Temp sensor panel design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
