Questions
How big is the IOT PCB PCB?
It measures 46 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IOT PCB use?
46 parts, built around the ESP32-S3-MINI-1-N8, RAC05E-05SKT, BME280 and ENS160-BGLM. 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 IOT PCB KiCad files?
From the theozor/EnvModulePCB repository on GitHub, at the commit this page was made from: the board is PCB/IOT_PCB/IOT_PCB.kicad_pcb and its schematic PCB/IOT_PCB/IOT_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IOT PCB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
