1 Foreword
1.1 Introduction
This document describes the electrical characteristics, RF performance, structural dimensions, and
application environment of the L610 MiniPCIe series module. With the help of this document and other
related documents, application developers can quickly understand the hardware functions of the L610
MiniPCIe module and develop product hardware.
1.2 Safety Instructions
By following the safety guidelines below, you can ensure personal safety and protect the product and the
working environment from potential damage. Product manufacturers need to communicate the following
safety instructions to end users. In case of failure to comply with these safety instructions, Fibocom will
not be responsible for the consequences caused by user misuse.
Road safety first! When you are driving, do not use a handheld mobile device, even if it has
a hands-free function. Please stop before calling!
Please turn off the mobile device before boarding. The wireless function of the mobile
device is not allowed on the aircraft to prevent interference with the aircraft communication
system. Ignoring the prompt may cause flight safety and even violate the law.
When you are in a hospital or health care place, please pay attention to whether there are
restrictions on the use of mobile devices. Radio frequency interference may cause
malfunction of medical equipment, so it may be necessary to turn off the mobile device.
Mobile device does not guarantee effective connection under any circumstances, for
example, when there is no prepayment for the mobile device or (U)SIM is invalid. When you
encounter the above situation in an emergency, please remember to use emergency calls,
and ensure that your device is turned on and in an area with strong signal.
Your mobile device will receive and transmit RF signals when it is turned on. RF interference
occurs when it is near a TV, radio, computer, or other electronic device.
Keep mobile device away from flammable gases. Turn off the mobile device when you are
near to gas stations, oil depots, chemical plants or explosive workplaces. There are
potential safety hazards when operating electronic device in any potentially explosive area.

The power stability ensures the normal operation of the L610 MiniPCIe series module. Pay attention to the
design that the power supply ripple should be lower than 300 mV (the circuit ESR is less than 100mΩ).
When the module works in GSM mode (burst transmit), the maximum working current can reach 2 A.

Ensure that the power supply voltage is not lower than 3.4 V, otherwise the module may be powered off
or restarted.

3.2.2 1.8 V Output
The L610 MiniPCIe 10 series module outputs a 1.8 V voltage through VDD_EXT for the internal digital
circuit of the module. This voltage is the logic level voltage of the module. It can be used to instruct the
module to turn on, and can also be used for external small current (less than 80 mA) circuit applications.
If not used, keep it floating. The logic level of VDD_EXT is defined in the following table.
