Hi Jaans,
Thanks for the dimensions. I decided I order az OS AC model, a TP-Link wifi device and the USB cable above, along with a micro USB converter and I will only modify anything in the housing if needed.
Now, IMHO the weakest point is the wifi router. I do hope the TP-Link stuff does not break my wifi network as it did for many others here and also hope it will not get cooked.
When I finish, my next project is to throw together a RPi based solution that regularly uploads my La Crosse OEM PWS data to Wunderground so I can access my own data with OS. 🙂
Thanks again for all the valuable information!
BR,
