    We have AM3517 SOM-M2 modules some with and some without the WIFI module populated.  We want to use a third-party WIFI module and use the UART2 port for communications to it.  This port is wired to the on board-WIFI module on the AM3517 SOM.

    1. Without the WIFI module installed on the SOM, is UART2 available for off-SOM use?
    2. With the WIFI module installed, UART2 would not be available, correct?

    Thank you

    Daren,

    1. Without the WIFI module installed on the SOM, is UART2 available for off-SOM use?

    Yes, UART2 is available on the following signals. That is because U26 and U27 bus transceivers are removed on SOM module where the WIFI module is absent.

    J1.93 UART2_TX
    J1.95 UART2_RX
    J1.91 UART2_RTS
    J1.89 UART2_CTS

    2. With the WIFI module installed, UART2 would not be available, correct?

    Correct, UART2 is not available with SOM modules when the WIFI module is present.
