The CPU board consists of a main printed circuit board assembly. It contains a 32-bit 800 MHz processor with a 256 MB non-volatile flash memory used to store the operating system (Windows EC7) and a 512 MB RAM. The real-time clock is backed up by a battery positioned on the CPU board.
The figure below shows the positions of connectors etc. The figure is followed by a list of all connectors and their use.
