Description
On Arduino Due schematics PDF file, "PD4" pin of the CPU is connected to "TXD0", and "PD5" is to RXD0. Then, in "Communication" header "TXD0" is to pin nr. 14, "RXD0" is connected to pin nr. 15.
While on the DUE printed board, pin nr. 14 is "TX3", and "pin nr. 15 is "RX3". The same is the naming in due's variant.cpp source file (this is Serial3).
So in Due's schematics PDF file, "TXD0" should be changed to "TXD3", and "RXD0" to "RXD3".
Contributor guide
Research direction
Locate the Arduino Due schematics PDF and inspect the Communication header labels alongside the Due variant.cpp source mentioned in the issue. Update the two schematic labels from TXD0/RXD0 to TXD3/RXD3, then verify the rendered PDF matches the board pin naming.
