External antenna through GPIO

Postby Thomaspapad » Sat Oct 28, 2023 9:07 am

Hey people. I m programming an esp32-s3-N32 devkit and i realized that the built in PCB WiFi antenna is not strong enough.. with just 10 meters and a wall I cannot connect to my houses WiFi.. the question is since there is no socket for an external antenna in this exact board and i really need the 32 Mb is there any way that i could connect an antenna through GPIO to enhance the signal?
Thank you in advance 😁

You cant do it with gpio but can make by scraping the solder mask on the esp module itself. Google " add external antenna to esp32" and you will see bunch of examples
