LARA-R2 Series - LTE Cat 1 modules in single and multi-mode configurations

Single and multi-mode LTE Cat 1 modules with positioning capability

LARA-R2 series modules support multi-band LTE-FDD with six regional variants. Each variant is designed for specific regional market requirements to allow development of cost-efficient yet feature-rich products. The variants with 2G or 3G fall back provide connectivity in cases where LTE coverage is not yet available. This allows seamless operation during technology transition.

With many interface options and integrated IP stack, the modules are designed to support a wide range of data-and-voice centric applications. The unique combination of performance, security and flexibility make them ideal for medium speed M2M applications, such as smart energy gateways, remote access video cameras, digital signage, telehealth and telematics.

LARA-R2 modules support Voice over LTE (VoLTE) or CSFB voice service for applications such as security and surveillance systems.

Thanks to u-blox CellLocate® technology, LARA-R2 offers cost-effective location estimation based on information from surrounding cellular base stations. A positioning solution with CellLocate and a u-blox GNSS module provides redundancy and accuracy that can be beneficial for numerous applications.

The temperature range of -40 to +85°C guarantees operation in harsh environments and in very compact designs


  • Cellular location service and Hybrid Positioning
  • Available in multi and single‑mode LTE Cat 1 configurations
  • Easy migration between u‑blox 2G, 3G and 4G modules
  • Small, compact LARA LGA form factor for easy manufacturing

EVK‑R2 kits are powerful and easy‑to‑use tools that simplify the evaluation of u‑blox TOBY‑R2 and LARA‑R2 series multimode LTE Cat 1 / 3G / 2G cellular modules, as well as an environment for designing and testing cellular and GNSS applications. The kits are very user‑friendly, providing a USB interface for development, testing and tracing. The kits come with a built‑in u‑blox GNSS receiver module, giving designers the flexibility to test either the LTE or the GNSS functionality. The kits are to be used with a Windows PC via USB interface, and require an activated SIM card (not included). USB drivers can be downloaded from u‑blox website.


Kit includes:

  • Evaluation board with a TOBY‑R2 series or LARA‑R2 series LTE Cat 1 module and a u‑blox GNSS module
  • USB cable
  • 2 cellular LTE antennas
  • GPS/GLONASS antenna
  • Power adapter
  • Audio headset
  • Quick start card
