I connected an external antenna to my UNO WiFi board, and I cannot
find information anywhere about if I have to make changes so that the
external antenna will be operative.
It looks like the on-board antenna is still active....
Hi.
Yes, I have the schematics, but not the board-layout.
I removed the internal antenna(X3), and added a link to the CX1 connector.
The modification works great.
Thank you Juraj for helping out.
