2. The LE910

2.1. Product Overview

The new Telit LE910 represents the next generation of Telit wireless connectivity with

xE910 form factor.

The LE910 combines the two cutting edge technologies HSPA+ and LTE. As a matter of fact,

LE910 is a 3.5G wireless data module offering HSPA+ connectivity with download speeds up

to 42 Mbps, and a 4G M2M module at the same time, providing an ultra high-speed downlink

at 100 Mbps.

The LE910 will be the first and smallest module in the market incorporating 2G/3G/4G

solution.

Designed for use in the most demanding industrial and consumer applications, the LE910

offers LGA packaging with cost effective mating solution. Three LE910 regional versions are

available, one for European, APAC and Latin American markets and two for the North

American market ( AT&T and Verizon configuration). All of them come with a multiband

configuration, covering different sets of 3G and 4G bands. Developers can take advantage of

Telit's xE910 Unified Form Factor that enables a “design once, use anywhere” strategy.

Due to its low profile, low consumption and advanced connectivity features, LE910 is

particularly suitable for applications such as mobile computing devices, PDAs, smatphones,

table PCS and counsumer or industial electronics in general.

Design your application once and choose the technology that best fits the regional

requirements for a truly seamless deployment. The LE910 is also fully backwards compatible

to existing EDGE and GSM/GPRS networks through integrated quad-band radios. Additional

features, such as integrated TCP/IP and UDP stack, DAC and ADC channels provide

extended functionality, adding value to the final application with no additional costs.

Moreover LE910 is also available with embedded GPS/GLONASS receiver and Antenna

Diversity. The extensive interface set, which includes USB, SPI, I2C and user definable

GPIOs, provides ease of integration of peripherals and actuators.

As a part of Telit’s corporate policy of environmenta protection, LE910 as all Telit products

comply with the RoHS (Restriction of Hazardous Substance) directive of the European Union

(Eu Directive 2011/65/EU).

LE910 Family Product Description

80421ST10587a- Rev.2– 2013-10-08

NOTE:

Some of the performances of the Telit modules depend on S/W version installed on the

module itself. The Telit modules S/W group is continuously working in order to add new

features and improve the overall performances. The Telit modules are easily upgraded by the

developer using the Telit Flash Programmer.

NOTE:

In order to meet the competitive OEM and vertical market stringent requirements, Telit

supports its customers with a dedicated Support Policy with:

 Telit Evaluation Kit EVK2 to help you to develop your application;

 A website with all updated information available;

 An high level specialist technical support to assist you in your development;

2.2. Target Market

The LE910 is designed and developed for applications requiring high throughput, devices

requiring worldwide coverage and for applications in areas such as telematics for in-vehicle

infotainment, video security and surveillance, outdoor signs and displays, business terminals

and consumer products such as routers, mobile hot-spots, etc.

4. Evaluation Kit

In order to assist the customer in the development of the application, Telit offers the EVK2

Evaluation Kit that can be ordered separately. The EVK2 has a SIM card holder, the RS 232

serial port level translator, a direct UART connection, audio and antenna connector.

The EVK2 provides a fully functional solution for a complete data or phone application. The

standard serial RS232 9 pin connector placed on the Evaluation Kit allows the connection of

the EVK2 system with a PC or other DTE.

The development of the applications utilizing the Telit LE910 family must present a proper

design of all the interfaces towards and from the module (e.g. power supply, audio paths,

level translators), otherwise a decrease in the performances will be introduced or, in the worst

case, a wrong design can even lead to an operating failure of the module.

In order to assist the hardware designer in his project phase, the EVK2 board presents a

family of different solutions, which will cover the most common design requirements on the

market, and which can be easily integrated in the OEM design as building blocks or can be

taken as starting points to develop a specific one.

For a detailed description of the Telit Evaluation Kit, please refer to the documentation

provided with the respective Hardware User Guide and EVK2 User Manual.

6. Safety Recommendations

READ CAREFULLY

Be sure the use of this product is allowed in the country and in the environment required. The

use of this product may be dangerous and has to be avoided in the following areas:

• Where it can interfere with other electronic devices in environments such as hospitals,

airports, aircrafts, etc.

• Where there is risk of explosion such as gasoline stations, oil refineries, etc. It is

responsibility of the user to enforce the country regulation and the specific

environment regulation.

Do not disassemble the product; any mark of tampering will compromise the warranty

validity. We recommend following the instructions of the hardware user guides for a correct

wiring of the product. The product has to be supplied with a stabilized voltage source and the

wiring has to be conforming to the security and fire prevention regulations. The product has to

be handled with care, avoiding any contact with the pins because electrostatic discharges may

damage the product itself. Same cautions have to be taken for the SIM, checking carefully the

instruction for its use. Do not insert or remove the SIM when the product is in power saving

mode.

The system integrator is responsible of the functioning of the final product; therefore, care has

to be taken to the external components of the module, as well as of any project or installation

issue, because the risk of disturbing the WCDMA/GSM network or external devices or

having impact on the security. Should there be any doubt, please refer to the technical

documentation and the regulations in force. Every module has to be equipped with a proper

antenna with specific characteristics. The antenna has

to be installed with care in order to avoid any interference with other electronic devices and

has to guarantee a minimum distance from the body (20 cm). In case of this requirement

cannot be satisfied, the system integrator has to assess the final product against the SAR

regulation.

The European Community provides some Directives for the electronic equipments

introduced on the market. All the relevant information’s are available on the European

Community website:
