2. OVERVIEW
Telit’s WE866Cx is a low power, high bandwidth 802.11ac and Bluetooth 4.2 module with
a small footprint that provides an easy and cost-effective way to achieve best possible
wireless connectivity. Advanced LTE, Wi-Fi and Bluetooth coexistence dramatically
reduces complexity designing cellular back haul with the LE910Cx 4G LTE module family,
making the WE866Cx module ideal for a wide range of IoT applications including
commercial building automation, OEM telematics, fleet management, and video
surveillance.
WE866Cx powered by the Qualcomm QCA9377-3 is a perfect companion device for Telit
LE910Cx cellular modules. WE866Cx supports low-power SDIO 3.0 interface for WLAN
and a UART/PCM interface for Bluetooth. WE866Cx also supports BT-WLAN coexistence
and uses the 2 wire ISM-LTE coexistence interface.
The following diagram shows a basic connection of LE910Cx with WE866Cx module over
the Wi-Fi interface.

4. HARDWARE
This section describes the hardware components of the LE910Cx +WE866Cx LTE module.
4.1. Telit Evaluation Board
The Telit Evaluation Board is a generic developer’s platform, which is designed to provide
the complete development environment to the user and intended to be used with a new set
of Telit IoT modules. The EVB is designed to carry an Interface Board (IFBD) via three 120-
pin B2B connectors. The Telit module is mounted directly on the IFBD. Power supply and
control interface to the IFBD module are provided from the EVB via the B2B connectors.
Several power supply configurations, including battery charging, are available. In addition,
all interfaces needed for the developers, such as SIM card holders, JTAG, UART, USB,
audio, micro SD, and so on are available on the EVB main board.
The following image shows an example of the generic Telit Evaluation Board.
Figure 4-1 Generic Telit EVB Board
4.2. Multi Technology Interface Board
The MultiTech Interface Board TLB (aka MTB) is custom designed to interface the Telit
module variant LE910Cx with the Telit Generic Evaluation Board (EVB) thus forming the
complete Development Kit of LE910Cx which allows great flexibility for integrating WIFI, BT
and GPS technologies with the LE910Cx.
The MTB provides the mapping of Telit module signals and functions into the generic EVB
signals and functions.
The MultiTech Interface Board TLB design includes the following items:
•LE910Cx module.
•3x M.2 type mini card slots.

LE910Cx-WE866Cx LTE Bundling User Guide
1VV0301578 Rev. 9 Page 17 of 56 2020-05-26
•Programmable FPGA.
•RF SMA connectors.
•Board to Board connectors for interfacing to EVB main board
•Module specific circuitry which is not part of the generic circuitry of the EVB
Power supply and control interface for the cellular module is provided from the EVB via the
B2B connectors.
To monitor the temperature, a thermistor is placed on the top GND plane, close to the
module which should be representative for the module’s backside temperature.
A programmable FPGA which is included in the MTB provides options for connecting very
functional modem pin to the relevant peripheral M.2 cards hence enabling the most flexible
way to demo interoperability between the LE910Cx module and peripheral accessories.
A typical example of this capability is in the case where 3x M.2 cards (WIFI module, GNSS
module and BT module) are plugged into the M.2 slots while the FPGA is programmed to
perform the correct signals mapping between the LE910Cx and the interfaces of each of
the M.2 accessories.
The following images show the MultiTech Interface Board top and bottom views:

For detailed description, refer LE910Cx Multi Technology Interface Board TLB –HW User
Guide.
4.3. WE866Cx M.2 Card
The M.2 card is designed to interface the Telit LE910Cx module family on an IFBD with the
Telit Generic Evaluation Board (EVB) thus forming a complete Development Kit of
LE910Cx.
The following image shows the top view of the M.2 card mounted with a WE866Cx module.

LE910Cx-WE866Cx LTE Bundling User Guide
1VV0301578 Rev. 9 Page 19 of 56 2020-05-26
The WE866Cx M.2 card follows the below M.2 specification:
•SDIO based Socket 1
•2230 size type
•Key type E
This form-factor card specification is intended to support Wireless Connectivity devices
including combinations of Wi-Fi, BT, NFC, and/or GNSS.
The card includes a U. FL miniature RF connector for connecting a compatible wi-fi antenna.
For detailed description of the M.2 Card, refer WE866Cx M.2 Interface Adapter Hardware
User Guide.
The following image shows the M.2 plugged into the MTB.
