Today I received my "Complete Starter Kit Neo2" with OLED-Hat.

I got scared that the screen can burn in - so is there any chance to set a timeout for the display after pressing a key?
I want to get the screen completly black after a special amount of time.

And how can I change the content of the shown screens? Like Celsius againt Fahrenheit temperature.
Or any other self designed text or infos?
(at which script should I take a look?
At the processes I can see Python, lcd2usb_print and NanoHatOLED....

BTW: Anyone else who had to solder the pins on Neo2-CPU-PCB in the "Complete Starter Kit"?
I did think - while seeing the assembly-video that we should get a soldered Neo2
Was my first solder-job for such a small pitch of solder-joints....but my Neo2 is alive with the OLED-Hat :)
