Board design questions #1

Closed wifixcort closed 3 years ago

wifixcort commented 3 years ago

Hi.

I have 3 questions about your board design:

  1. Why do you use 2 F.Cu and 2 B.Cu Zone outlines instead of just use one for each side? 2.There is a espetial reason for use 0.508 clearance instead a smaller one 3.You make a big loop on 5V or A4 pin in the USB connector, is that really needed, because fisically is the same pin, I think it's not necesary, or I'm wrong?

If you change the rotation of some components it turn out a simplier PCB routing

Hi @wifixcort

1.- An error when designing does not affect anything but we will remove 2.- It is just the design standard we use 3.- double connection is necessary for USB-C

Welcome to contribute if you consider the design can be improved, we look forward to your pullrequest
