 ''TBDThe Evaluation Kit is powered by one of the USB Type-C connectors. To properly power the system the wall adapter must support the [https: sostituire le sezioni con le informazioni sull'uso della periferica e del suo connettore''''Nell'esempio di seguito c'è la descrizione dell'interfaccia UART/console''/en.wikipedia.org/wiki/USB_hardware#USB_Power_Delivery power delivery] protocol.

The Power Supply interface available on the Evaluation Kit at the connector ''TBD:JxxxJ3''.

''JxxJ3'' is a ''TBD:connectorUSB Type-typeC'' header connector for the RS232 two-wires UART3 portUSB3 data transfer and board supply, used for debug purposes (bootloader and operating system serial console).

=== Device mapping Power LED ===UART3 DL2 is mapped to <code>/dev/ttymxc2</code> device in Linuxa green LED (placed near the reset button) that shows the status of the power input. The peripheral This LED is ON when a valid power supply is used as present and the system is out of reset. === Alternate supply ===An auxiliary connector is present on the board (not mounted by default serial console, both ) to power the system with a standard power supply. This connector is meant for developing purpose (eg when the bootloader SW is not already able to handshake a valid PD profile) and the kernelcannot be mounted for some Evaluation Kit models.

=== Device usage =Description ====Power can be provided through the J20 connector. Power voltage range is +[12-24 V].
