Questions
How big is the Weather Kit Project PCB?
It measures 85 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Weather Kit Project use?
98 parts, built around the WIO-SX1262, TPS631000DRL, BQ24230RGTR and MAX-M10S. 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 Weather Kit Project KiCad files?
From the Mikecerc/WeatherKit_MainBoard repository on GitHub, at the commit this page was made from: the board is Weather_Kit_Project.kicad_pcb and its schematic Base_Station/Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Weather Kit Project design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mikecerc before reusing the design.
