Topic: Serial Port for MR3420V2

The content of this topic has been archived on 2 May 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

Can anyone point out the Tx and Rx pins on the MR3420V2 Router?

The board layout is different.
MR3420V2 runs on AR9341 533MHZ Atheros while V1 runs on AR7240.
I suspect the bottom 2 is TX/RX just want to be sure since someone already succeeded.

The discussion might have continued from here.
