Miscellaneous

SSD (Solid State Drive)

The CoreModule 745 provides a standard SSD, which is a storage IC soldered directly onto the board. For
more information, refer to the SSD data sheet: http://www.greenliant.com/products/?inode=46780.

Real Time Clock (RTC)

The CoreModule 745 contains a Real Time Clock (RTC). The RTC can be backed up with a battery. If the
battery is not present, the board BIOS has a battery-less boot feature to complete the boot process.
