Overview

The Boolean board is an educational platform built around a Xilinx Spartan-7 FPGA. It includes a large collection of peripheral devices and ports, allowing countless designs to be built without the need for any other components. A single USB port that provides power and a programming port allows the board to integrate seamlessly with the Xilinx Vivado design tools. It is well suited for teaching digital design.

What is included?

  • The board featuring Xilinx Spartan 7 XC7S50 FPGA

Suggested use of this board

  • Exercises ranging from a simple digital circuit to complex system
