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


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:

Hi, I can help on this. I can tell you missed some parts on the schematic. Why did you already make the design before having the schematic checked? Regards, Michel
