USB
The GESBC-3130 Single Board Computer provides one high speed USB OTG port. The USB On-
The-Go block enables usage in both device mode and in host mode. This means that you can
connect to a PC to exchange data, but also to another USB device such as a digital camera or MP3
player. The USB port are brought out by a USB type A/B mini connector.
RS-232 Port
The GESBC-3130 Single Board Computer is shipped with one fast RS-232 UART interface. The
fast UART on the GESBC-3130 serves as a debug port by U-boot and Linux kernel. The UART
connector is the DB-9 connector on GESBC-3130. The signal designation is listed in the
following table.
