c.The 13pin pin header on the Orange Pi R1 Plus LTS Zero 2 development board can be connected to the interface expansion board to expand the functions that are not available on the development board. The functions included in that the interface expansion board arecan use include:<br>{| class="wikitable" style="min-width:800px;text-align:center;"
