Serial console pinout? - jlucas - 09-01-2022
Hey I found some contradicting information on the wiki regarding the serial cable pinout:
In this wiki page it says that the tip is RX and the ring TX.
But right below it links to this PDF which says the opposite - tip is Tx and ring 1 is Rx.
Which one is correct?

If in doubt check the schematic. For v1.1 (Brave Heart) it shows headphone connections going via switch U801 which handles the change between audio and serial use. Tip HP_L goes to PB9-DEBUG-RX (A64 PB9/UART0-RX) and ring (HP_R) to PB8-DEBUG-TX (A64 PB8/UART0-TX)
The source of the confusion might be which RX and TX are being discussed - the cable doc may be talking about the RX and TX of the usb-to-serial adapter rather than the PineTab's.

Oh ok that makes sense.
Thanks for the explanation.
