The SARA-R52 series is the next evolution of u-blox's SARA-R5 modules, built upon the foundation of the u-blox UBX-R52 cellular chipset and the u-blox M10 GNSS receiver chip. With complete control over all technology components and comprehensive hardware and software ownership, u-blox ensures enduring device availability and ongoing support at every level, including down to the chipset level.
These modules embrace LTE Cat M1 and LTE Cat NB2 technologies, leveraging a rich suite of features from 3GPP Rel. 14 and Rel. 15 tailored for IoT applications. This encompasses enhancements in power efficiency, coverage, data rates, and mobility. Equipped with an integrated uCPU, users can execute their applications directly on the UBX-R52 chipset, eliminating the need for an external MCU.
The SARA-R52 series offers two variants: one for general LTE connectivity and another featuring an additional GNSS receiver. The SARA-R520M10 variant integrates the u-blox M10 GNSS receiver, delivering superior positioning data alongside LTE communication, ideal for continuous or cyclical tracking applications. Meanwhile, the SARA-R520 model incorporates SpotNow for location information, a cost-optimized positioning feature powered by the UBX-R52 chipset, eliminating the necessity for a separate GNSS receiver. SpotNow employs a power-efficient assisted GPS receiver solution, tailored for intermittent tracking scenarios.
Security is paramount with the SARA-R52 modules, featuring secure boot, secure updates, and secure production implementations. All versions support u-blox's communication services – MQTT Anywhere or MQTT Flex – which reduce data overhead, airtime, and energy consumption, thereby extending device lifecycles, reducing costs, and enhancing ROI. Furthermore, the SARA-R52 series holds qualifications from AWS IoT Core and certification from Microsoft Azure.
