2 FPGA Development Board Hardware and I/O Features
Each of the five different FPGA boards (DE1, DE1, UP3, UP2, and UP1) have
a slightly different feature set of logic, I/O interfaces, memory and other
assorted hardware. As long as the FPGA board has enough logic and it has the
required I/O features, a project can be implemented on any of the boards.
FPGAs are available in a wide range of sizes with different feature sets. In
general, FPGAs with more logic, more I/O pins, higher speed, or more memory
are more expensive. When designing new products, choosing the FPGA with
the proper feature set at the lowest cost is an important design consideration.
