==Power Supply interface ==
''TBD: 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''
=== Description ===
The Power Supply interface available on the Evaluation Kit at is provided through the J16 connector ''TBD:Jxxx''.  ''Jxx'' Power voltage range is a ''TBD:connector-type'' header connector for the RS232 two+[12-wires UART3 port, used for debug purposes (bootloader and operating system serial console)24 V].
J16 is a two pins 2x3.5mm 691321100002 Wurth connector.

=== Device mapping Power LED ===UART3 DL3 is mapped to <code>/dev/ttymxc2</code> device in Linux. The peripheral is used as the default serial console, both for a green LED (placed near J16) shows the bootloader and status of the kernelpower input. === Device usage === To connect to the debug serial port: # connect the DB9 adapter bracket to the J22 connector on the SBCX board# connect This LED is ON when a serial cable between DB9 connector and PC COM port through a NULL-modem cable (not provided)# start your favorite terminal emulator software on PC (eg: PuTTY); communication parameters are: 115200,N,8,1valid power supply is present.
