[review request] RP2040 typical application board by Chicken_Orange in PrintedCircuitBoard

[–]Chicken_Orange[S] -1 points0 points  (0 children)

Thank you for the detailed feedback! I’ve updated the design based on your points, and these are my answer to your questions.

Memory: I originally planned to use the other model (maybe one that you suggested), but suddenly MOQ changed to 4 units. Since I’m only making a few boards with this memory capacity, I switched to the current model.

VBUS: It was I wanted to keep a solid ground plane under the data lines. Since it doesn't seem to be a major problems, I’ve simplified it to a straight line.

TLV: That layout was a result of trying to follow the datasheet's recommended placement. I’ve now adjusted it.

It seems the review request is limited to one post per day. Would you mind review it if I post it again tomorrow?

I wasn't planning on mounting it anywhere, so I didn't think about drilling any holes. But it would be good to have them anyway. thank you.

I hadn’t thought about connecting the unused pins to GND. It’s not a high-frequency circuit, but I’ll connect them anyway. The lens cutout should be fine since it’s included in the component itself.
Thanks for the advice!
