Review my PCB design - a audio shield for a ESP32 dev board

Hi,

i have created a shield for a ESP32 dev board and before i send it to production i would like to get a second opinion on it.

It is a audio recorder with a LiFePo4 MPPT solar charger for a 6V panel. So noise should be considered even though a digital microphone (I2S) will be used.

Here is a link to the design:
