i have a SparkFun GPS-RTK Dead Reckoning Kit (SMA) Sensor Fusion GPS Board, 184-channel u-blox F9 Engine GNSS Receiver. I am trying to determine the uart rx2 pin on the board. i am connecting to the rx12 pin but not sure that is really rx2. i am using the rx1 pin for another data stream. I see another post where it is suggested to push in uart1. i would really rather use uart2, is the pin labeled rx12 the uart 2 receive . i am sending (ntrip)rtcm stream from my pi

The pin you’re looking for is labeled RXi2, “i” meaning data in. It’s beside the pin labeled TXo2 where the “o” means data out.

thanks, guess i couldn’t make out the difference between the i and a I . that’s what i wanted to confirm that this is uart2 receive.
