PCI Express Mini Card Socket
The UNO-2484G single-stack model supports one full-size socket for PCI Express
mini cards.The (MINI1) interface supports USB, PCIe, and mSATA signals and can
automatically detect the device type to provide the required support. This function
can be accessed via Wi-Fi, 3G communication module, or mSATA SSD.
The UNO-2484G double-stack model combines a single-stack model with an UNO-
2484G-EKAE extension kit. In addition to the mini PCIe slot on the first stack, the
double-stack model also supports three additional full-size PCI Express mini card
sockets on the second stack. The MINI1 interface on the second stack supports USB
and PCIe signals. The MINI2 and MINI3 interfaces only support PCIe signals.
Note!
In addition to the mini PCIe (MINI1) socket, the system features a SIM
card slot for supporting 3G/LTE functionality. However, users are
required to install a 3G/LTE mini PCIe module to enable this function.
