==UARTs interface ==
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
The RS232, RS485 and CAN use the standard protocols.
