OPENMV special expansion board, official open source engineering expansion board

Introduction: The PCB is based on the official expansion board layout and published schematic drawings. The layout and packaging are almost the same as the official board. The pin definitions and functions are the same as the official ones. Friends who want to DIY can build the board by themselves, and there are a few more. I'll give it a try and I'll continue to finish it.
