Description
Made for Fallout during a online weekend hackathon
Why did i make this
I always had this idea, because i never know what to wear outside before leaving my house and I can't be hassled to check the weather app, so i will place this at the door window, so i can look and and check the temperature and other weather stats before leaving.
How to build
Download the Gerber files and the 3d models and print them out. (I recomend JLCPCB and Prining Leigion). Order all the parts from the BOM section. After everything arrives solder the components togeather with the board and put the PCB in the case and Screw it in with a 2mm Screw. After close the box and screw it in with 3mm Screws. Connect the ESP32 to your computer and flash it with the firmware.
How to use
After flashing it, turn the ESP32 back on and it should start automaticly. If everything worked out it should start showing the data on the OLED screen.

Questions
How big is the EasyWeather PCB?
It measures 32 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EasyWeather use?
5 parts. 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 EasyWeather KiCad files?
From the AronTheB/EasyWeather repository on GitHub, at the commit this page was made from: the board is PCB/EasyWeather.kicad_pcb and its schematic PCB/EasyWeather.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EasyWeather design in my own project?
Its repository states no licence, so its author keeps all rights: ask AronTheB before reusing the design.
