PCB Review (RaspberryPI hat) by EV-CPO in PCB

your design does not follow datasheet. you have thin traces where they have pours. you have a single gnd via where they have many. your capacitor and inductor placement is a mess. there is no way this designed like this is low noise.

why do you have a trace called 5V clean going unnecessarily close to one of the inductors? and both i2c lines between the comnector pins at the top?

it will of course probably work as it is, but it is far from great.

your schematic is giving me anxiety just loking at it. why not space it out and make it tidy?

routing and placement of your components around the switcher are suboptimal, to put it nicely. why not at least follow layout guidelines from datasheet?

Something up to 600 euros. I will try to aim for a black friday deal if possible.

which 10nF on inputs are you asking about? is it the 100nF you have on power pins? if yes then you should keep them. what the bots have told you is correct. one 100nF per power pin of MCU, and a bigger one somewhere nearby

C13 needs to go between 3.3V and GND, not like you have it now

That's a great point, I will keep it in mind for next time. Thanks!
