I've received my board today, it's a nice small board but there's one thing unclear to me, it's the pin named P30 on J2 connector. According to the user's manual, it's named PE0, not P30. Can someone please answer me what that pin is? Is it PE0 or other pin?
thank you in advance (and please forgive my bad English)
It is PE0 (pin 9). You can follow the signal path quite easily. There are two vias related to this signal: one is near to label PF0, the other is covered by letter P of the label PA4.
I think, the P30 name is just a typo in the silk design.
Istvan is correct, it's just a silkscreen typo. P30 on the silkscreen is actually PE0 in the layout.
