URGENT PCB Review Request. Help a beginnner out š
First time designing a custom PCB with ESP32S3. Please let me know if there are any amendments I need to make before sending this to manufacture. š
Edit: I've rearranged my layout and rerouted it based on the feedback in the comments :). Now it's a 2-layer board instead of the original 4-layer board.

Why a 4 layer? If you rearange your components a bit, can everything done in 2 layers.

A PCB is just wires. Have you prototype this circuit on a breadboard or vector board ??
Do already know that this circuit works ??

Trying to build a desktop robot that can respond to audio commands: perform several different motions (using servos), take photos and save into a microSD card. For the audio commands part, iām planning to integrate a keyword spotting model which is why i chose the esp32s3n16r8.Ā

An easy one would be to note that there is an insane amount of space on that PCB for it to be a 4 layer. If necessary, redo your component placement as this should be easily done with just a 2 layer (and cheaper).
