which WIFI dongle to choose in 2021

Hello,

I am looking for a WIFI dongle for my new Redpitaya (STEMlab 125-14). I know that a WIFI dongle with a RTL8188CUS chipset should work. However, I am not able to buy one, because I am limited to the German market, and there are no dongles with RTL8188CUS to find. (At least according to my research.)
My question is: Does anyone know a WIFI dongle that is available in Europe (Germany) and works out of the box with the normal image?
I would be very happy about a short feedback.

I have already tried the following dongle without success:
EDI EW-7811UN V2
TPLINK TL-WN725N
TRN TEW-648UBM

With kind regards,
Max

Red Pitaya documentation still recommends using the ten-year-old version of Edimax EW-7811Un:

Looks like it still can be ordered from amazon.de:

However, I think a better strategy would be to contact Red Pitaya support and ask them to update the OS and add more Wi-Fi drivers.
