For development purposes, please use the LE910C4-EU MTB Interface Board together with Telit's Motherboard EVB (Rutronik Order Code: GSM1797) and the WE866C3-P M.2 Aadapter Card (Rutronik Order Code: WLAN1646).

General Description:

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

• 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 every 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.
