5.1 Features
5.1.1 Watchdog Timer
The Watchdog Timer function allows your application to regularly “clear” the system at the set time
interval. If the system hangs or fails to function, it will reset at the set time interval so that your system
will continue to operate.
5.1.2 DDR3L
DDR3L is a higher performance DDR3 SDRAM interface providing less voltage and higher speed
successor. DDR3L SDRAM modules support 1600MHz for DDR modules. DDR3L delivers increased
system bandwidth and improved performance to provide its higher bandwidth and its increase in
performance at a lower power.
5.1.3 Graphics
The integrated Intel® HD graphics engine delivers an excellent blend of graphics performance and
features to meet business needs. It provides excellent video and 3D graphics with outstanding graphics
responsiveness. These enhancements deliver the performance and compatibility needed for today’s
and tomorrow’s business applications. Supports 1 x DDI (HDMI/DVI/DP++) and 1 x LVDS/eDP
interfaces for display outputs.
5.1.4 Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of up to
6Gb/s (SATA 3.0), it improves hard drive performance faster than the standard parallel ATA whose
data transfer rate is 100MB/s.
5.1.5 Gigabit LAN
The Intel® I210AT Gigabit LAN controller or the Intel® I210IT Gigabit LAN controller supports up to
1Gbps data transmission.
5.1.6 USB
The system board supports USB 3.0, capable of running at a maximum transmission speed of up to 5
Gbit/s (625 MB/s.
