Review my PCB design - a audio shield for a ESP32 dev board
Budget: $10 – $30 USD
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:
