Ordered, but still not tested:
- The Pi Hat USB WLAN adapter for Raspberry Pi
Did I then downloaded NOOBS and copied to the stick, put together everything and hochegefahren "System", Raspberian selected and installed to install. All without spec. So should be!
System started immediately with 1024x768'er resolution.
(For the VGA adapter I used no possibility still specially to connect a power supply that was like that. But I am still glad that the adapter provides the option of connecting a power supply)
Raspberian launched after installation without any problem and was not sooo slow when you open the window, as I feared (and otherwise read) had. Well, in the basic configuration is indeed not much.
More can be up here, I think, do not expect.
