The J3 and J4 are USB Ports interface available on Type-C connectors. J3 is also used to supply the system, see [[ORCA SOM/ORCA Evaluation Kit at the connector ''TBD:Jxxx''/Interfaces and Connectors/Power Supply|Power Supply]] section.

''Jxx'' is a ''TBD:connector-type'' header connector for the RS232 two-wires UART3 Both ports can provide 5V output up to 2.2A. J3 port, used for debug purposes (bootloader and operating system serial console)can also be configured to provide up to 3.3A

The following table describes the interface interfaces signals:

 To connect to the debug serial portThe USB ports can be used under Linux for connecting USB devices: # connect the DB9 adapter bracket related device driver has to be integrated into the J22 connector on the SBCX board# connect 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,8,1Linux kernel.
