Mini PCIe and SIM card socket
Two Mini PCIe connectors for full-size Mini PCIe cards (50.95 × 30 mm) are provided on the MBa6ULxL.
Every standard Mini PCIe card can be used
. USB_H3, USB_H4, and I2C4 are routed to the connectors, see Table 21.
A SIM card socket to connect an UMTS / GSM modem is available.
The following block diagram shows the interfaces to Mini PCIe 1 and Mini PCIe 2.
