Diy_de2 development board Introduction

Altera officially has a de2 Development Board, which has rich resources and complete peripherals. It uses ten-layer circuit board design, and the price is naturally high. I made a piece based on the principle diagram, called diy_de2 Development Board. The Development Board uses the core board and bottom board mode for ease of use and can be used in subsequent projects. The core Board uses a 6-layer PCB, while the bottom board uses a 2-layer PCB. The shape of the Board is as follows.
