2.6.1 Mini PCIe Port

i.MX 8M Mini SODIMM Carrier Board supports Mini PCIe connector to support Mini-PCIe device. Optional 0E resistor R166
for PCIE_RXM and R170 for PCIE_RXP has been populated at the connector receiver signal side for PCIe device coupling
option. Mini PCIe connector (J20) is physically located at bottom of the board as shown below
Note: Either Mini PCIe connector or 2
