2.3.12 Mini PCIe3
The SIGM-3250 mainboard (STX-I907) also provides 1*Mini PCIe pin spacing 5.2mm interface (Mini
PCIe2) with USB signal. When 2*CAN is selected, this Mini PCIe slot is occupied. Devices with USB
signals can be extended, such as CAN Bus. The Mini PCIe2 interface definition is shown in table 2.14.
