Good morning, everyone. I am playing with GUITION 4” 480x480 ESP32-S3-4848S040 Smart Display with LVGL and would like to use this one for my Master Bedroom. Is it possible to add a microphone and speaker to use like a voice assist ?
Here is a picture of the back side of the board:

It already has a speaker port built in but adding a microphone would require hardware modification and very careful soldering!
I can do this, but what about code? It will take a regular ( what I have n the screen) and voice assist for esp32-s3?
I try to find a pinout for this devices to connect or solder a microphone, but couldn’t find any documentation. Any idea or maybe references to this information? TY
edit:
I found this info on espressif.com, but not sure which pins is better to use for I2C mic.

you can add an I2S microphone on the same pins of speaker driver
