This case was designed to hold most KeeYees WiFi ESP8266 Weather Station Kit components and enable the user to hold business cards on its sides. The Programm Code is on their Website. http://www.keeyees.com/a/Download/ I also added the documantation in this post because you need to register if you want a building guide and dont forget to change the degree Symbols because the format is wrong if you copy and paste the code. Also you need to drill the OLED hole with a M3 Drill and you need araound 4 M3 Screws to secure the componente.
