NB2DSK01 Motherboard Resources
Altium's Desktop NanoBoard NB2DSK01 is a 300 x 165mm (11.8" x 6.5") eight layer printed circuit board (6 x signal, 2 x plane), powered by an external 5 Volt regulated supply. One of the plane layers is associated exclusively to GND. The other plane layer is used primarily for the 3.3V power supply, but incorporates a split region to accommodate the 5V supply. Both top and bottom of the board are used for component placement.

The NB2DSK01 motherboard features a variety of resources, many of which are made available to the target FPGA on the currently-fitted daughter board. There are also a number of system resources, that are not accessible from a daughter board device, but are available to the user in various situations – such as connectors for daisy-chaining NanoBoards, audio-related connectors, and resources for powering the board. Some system resources are only used by the NB2DSK01 itself, such as memory devices used by the firmware running in the board's Controller FPGA device.
Additional resources are available to a daughter board device, located either on the daughter board itself (e.g. memories) or on dedicated satellite extension boards that also plug-in to the NB2DSK01 motherboard. The latter are referred to as peripheral boards. Further information on daughter and peripheral boards can be found in Daughter Boards and Peripheral Boards respectively.
Note: For each resource, reference is made to the corresponding sheet(s) of the motherboard schematics on which the circuitry of interest can be found. For a pdf document of these schematics, see NB2DSK01 Desktop NanoBoard Schematics.
Resources Accessible from an FPGA Design
The NB2DSK01 motherboard has a variety of resources individually wired to target daughter board FPGA I/O pins. These allow a wide variety of embedded examples to be executed on the NB2DSK01, in addition to providing a base for developing new applications.
The following linked pages detail those resources on the NB2DSK01 motherboard that can be accessed from, and used within, a design targeted to a daughter board FPGA device:
