ESP32­_PICO_­D4
I use a 1/4L antenna. Do I need an additional balun, or can it be connected directly to the module?
thanks for the information

Hi,

You don't need an external balun since you already have one inside the ESP32. You need just to consider the antenna matching circuit.

I am using a quarter wave antenna. I believe - it can be connected directly to ESP32­_PICO_­D4
