pinout information.
2.3.4 Ethernet Port
The Ethernet port is routed from the SBC module to the IO connector through the
COMExpress
®
connector on the carrier board. The carrier board supports 1Gb/s,
100Mb/s and 10Mb/s, but only the speeds supported by the SBC module will be
available at the external connector. Link and Activity LEDs on the front panel indi-
cate connection and link speed. The Activity LED blinks at different rates depending
on the link speed.
2.3.5 Video Port (VGA)
The VGA port comes straight from the SBC module, with filtering and ESD protec-
tion provided on the carrier board. DDC interface and VGA power is provided. The
DDC interface allows the CPU to probe the monitor and download its display capa-
bilities. VGA power can be either 3.3V or 5V, set by factory solder bead setting, with
fuse protection.
2.3.6 Storage
The carrier board hosts a 32GB Solid State Disk (SSD) attached to the SATA0 link
of the CPU module. This device can sustain a 3GB/s speed rate. It complements the
storage on the CPU module itself, (1GB DDR3 SDRAM and 2GB FLASH), and can
be used as the boot device for the system. Storage access activity is indicated by an
LED on the front panel.
