The UARTs interfaces available on the RIALTO SBC are mapped to the following connectors:

* J42 is a Phoenix 4x1x2.54mm pin header connector. On this connector is mapped the <code>console</code> interface (UART1).

~~[[File:RIALTO-SBC-console-connector.png|thumb|center|500px|Console connector]]~~

* J66 is a Phoenix 282837-3 3x50.8mm connector. On this connector are mapped these instances: UART3 or CAN.

The following tables describe the interfaces signals:

=== Device mapping ===

~~UART1 is mapped to <code>/dev/ttymxc0</code> device in Linux. The peripheral is used as the default serial console, both for the bootloader and the kernel.~~

RS232 is UART3 and it is mapped to <code>/dev/ttymxc2</code> device in Linux
