Sara-R52

Compact LTE-M / NB-IoT modules with integrated positioning, onboard application support, and secure, power-efficient communication for advanced IoT deployments.

Sara-R52 overview

The Sara-R52 series is the second generation of LTE-M / NB-IoT modules based, offering low-power cellular connectivity with flexible positioning options and built-in application support. With full hardware and software ownership, the platform ensures long-term availability and support down to the chipset level. The series supports LTE Cat M1 and NB2 across 3GPP Rel. 14/15 and includes variants with integrated power-optimised SpotNow location features. All modules support MQTT Anywhere and MQTT Flex and are qualified for AWS IoT Core and Microsoft Azure.

Benefits

Application-ready architecture

Run customer applications directly within the R52 chipset, reducing hardware complexity and cost.

Efficient positioning

Enables low-power, cost-effective location tracking with SpotNow, ideal for occasional or power-sensitive tracking.

Low power, long life

Supports 3GPP Rel. 14/15 features such as PSM, eDRX, and power-optimised connectivity to maximise battery life.

Secure by design

Delivers secure boot, secure firmware updates, and secure production implementations for robust device protection.

Built-in IoT cloud services

Out-of-the-box compatibility with MQTT Anywhere and MQTT Flex reduces airtime, overhead, and energy consumption.
