Pi filter for wifi antenna

[rkumararora]

Hi,

I have tested ESP32-wroom module for Wi-Fi communication, and it is working fine. Now I want to create my custom schematic using ESP32 controller. I want to know the values of CLC network used in WROOM module for Wi-Fi Antenna. Also, it will be helpful if someone gives more idea about the PCB antenna used in that module.

Please be noted those CLC value vary with board, so you should tune them with your board, the values from our module will not help more than starting from 0.
You could refer to ESP8684 hardware design guidelines to see more information about RF tuning. ( we will update same part in ESP32 HDG,the information applys to all chip series )

Hi,

I agree to start with 0 and then tune the values. But I want to start with some defined values because I am using exactly same geometry for antenna and other things in WROOM module.

Hello,

I found this video that can help : https://youtu.be/yxU_Kw2de08

I wish Espressif hardware design guides were more verbose about that stuff...
