Design Resources


The SARA-N2 NB-IoT module features extremely low power consumption in both idle and connected modes of cellular operation. It is available in a small LGA form factor and has been designed explicitly with the needs of battery powered applications that need to communicate for long periods of time in challenging radio propagation conditions.
The module supports a comprehensive set of communication protocols including SMS, IP and efficient IP-less data transmission all with minimal signaling overhead to preserve power consumption. The feature set makes these modules ideally suited for applications where longevity of operation and reachability in poor propagation conditions are mission critical. Smart water metering, smart gas metering, smart sensors for remote monitoring and nomadic asset tracking are perfect examples of applications where this module could be used.

The SARA-N2 module targets high volume, cost sensitive applications, and provides “bit pipe” communication functionalities while minimizing the customer’s total cost of ownership. SARA-N2 offers easy migration from u‑blox GSM (SARA-G3 series), UMTS (SARA-U2 series), as well as LTE Cat 1 (LARA-R2 series) modules.
The temperature range of –40 to +85 ° C guarantees operation in harsh environments and in very compact designs. The modules are for global use and will be certified and approved by the main regulatory bodies.
The modules are manufactured in ISO/TS 16949 certified sites, with the highest production standards and the highest quality and reliability. Each module is fully tested and inspected during production.
