Product Description

The V3 variant of the GL865-DUAL is based on the latest chipset technology, designed to protect your design invest­ments as a low-cost, long-term availability solution. It is recommended for any new cost-sensitive designs requiring 2G GSM I GPRS coverage and long term application cost stability, such as security alarms, automated meter read­ing, and POS terminals.


The new generation GL865-DUAL V3 operates with 1.8 V GPIOs versus its predecessor's 2.8 V, minimizing power consumption and making it even more ideally suited for battery powered and wearable device applications. Embed­ded Python Script Interpreter in the GL865-DUAL V3 makes it possible to run the customer's application inside the module making it a complete SMT platform for m2m solutions.


An optional factory mounted m2mAIR embedded SIM-chip is available.

Family Concept

The Telit xL865 family was conceived to address system integrators and developers needing to start with low volumes (LCC mount) as well as those already running high volumes (VQFN mount). Its ultra-compact pack- age allows integration into very small devices. The family includes products that are pin-to-pin and API compatible in GSM I GPRS, CDMA I 1xRTT and UMTS I HSPA.


loT LOCATE is a Telit portal-based service that provides a device's position based on observed cellular Cell-IDs. Accessing a database of over 40 million cell-IDs globally, loT LOCATE can provide a position for every use-case including indoors/underground, outdoors, and boundary situations.

loT Connectivity Ready

This product is capable of supporting the extensive suite of loT Connectivity value-added services and connectivity you can use to enhance your application and boost your competitive advantage.
