The Network Gateway (NGW) is a fully functional embedded computer system.

The circuit board have a flexible power system that accepts 9-15V DC input. The on-board DC/DC converters create core voltage for the CPU and the system voltage used on the rest of the board.

The Network Gateway have a total of 16MB flash and 32MB of SDRAM. The on-board memory can be expanded through the SD/MMC slot by insertion of either a SD card or a MMC card. The system is able to boot Linux from the on-board flash. Expanding the size of the memory allows developers to try out Linux programs with larger memory footprint than the size mounted on-board.

Three communication interfaces are available from the NGW. The RS232 interface is usable for low level debugging like communicating with the boot loader. The network interfaces are essential to show networking capabilities of the AP7000 processor and the USB connection allows you to explore the USB 2.0 capabilitiy of AP7000.

The JTAG connector is used for programming of the on-board flash and for debugging. High-end emulators using the nexus interface can be connected to the NEXUS port if this connector is soldered in.

The expansion connectors provide developers access to unused interfaces from the AP7000 processor. This allows developers to create add-on boards with expanded functionality.
