2 General Description 2.1 Overview EG91 miniPCIe is a series of LTE category 1 module adopting standard PCI Express Mini Card form factor (Mini PCIe). It is optimized specially for M2M and IoT applications and delivers 10Mbps downlink and 5Mbps uplink data rates. EG91 miniPCIe supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BeiDou, Galileo and QZSS). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning.

2.14 Power Saving 2.14.1 Sleep Mode EG91 Mini PCIe can reduce its current consumption to a minimum value in sleep mode. There are three preconditions must be met to make the module enter sleep mode. • • • Execute AT+QSCLK=1 to enable sleep mode Ensure the DTR is kept at high level or be kept open The host’s USB bus, which is connected with the module’s USB interface, enters suspend state 2.
