Design Resources


LARA-R2 series modules support multi-band LTE-FDD in a very small LGA package.
The modules are ideal for applications that are transitioning to LTE from 2G and 3G, due to the long term availability and scalability of LTE networks.
With a range of interface options and an integrated IP stack, the modules are designed to support a wide range of datacentric applications. The unique combination of performance and flexibility make these modules ideally suited for medium speed M2M applications, such as remote access video cameras, digital signage, telehealth and telematics.
They also support Voice over LTE (VoLTE) for applications where voice is required such as in security and surveillance systems.
The temperature range of –40 to +85 ° C guarantees operation in harsh environments and in very compact designs.
The ultra-compact LGA package enables straightforward automated manufacturing. The LARA form factor follows the u‑blox nested design principle and is compatible with u‑blox SARA, LISA and TOBY module families. This facilitates easy migration from u‑blox GSM/GPRS, CDMA, UMTS/HSPA, and multi-mode LTE modules, maximizes the investments of customers, simplifies logistics, and enables very short time-tomarket.
LARA-R2 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. Modules are qualified according to ISO16750 – for systems installed in vehicles.
LARA-R2 modules come in variants for America and Europe.
USB drivers and RIL software for Android are free of charge.
