Hi
I am using USB type b v2 in full speed using microcontroller pic18f4550 I
will be designing double sided pcb I have following query
1 are there any layout guidelines for USB v2 full speed ?
2 will the USB trace d+ d- needs to be impedance controlled ?
3 if yes then what should be the impedance for double sided pcb and how to
calculate it. ?
I read about guidelines for high speed but not sure if that's same for full
speed ?
Thanks for the help...
Best regard
