At 16 x 26 mm, the SARA‑R4 series modules provide an ultra‑compact LTE Cat M1 / NB1 and EGPRS multimode product in a single hardware design. They have software‑based LTE band configuration, and come in an LGA package for easy manufacturing.

The SARA‑R410M and SARA‑R412M variants simplify diverse deployments worldwide and provide enormous operational efficiencies. Software‑based configurability of operator profiles and LTE bands enables a wide range of multi‑regional coverage. The flexibility extends further through system selection as LTE Cat M1, LTE Cat NB1, EGPRS single or preferred modes. Customers can future‑proof their solutions by means of OTA firmware updates, thanks to the uFOTA client/server solution, which utilizes LWM2M, a light and compact protocol ideal for IoT applications.

 The two SARA‑R4 (x3B) module variants – SARA‑R410‑63B and SARA‑R410‑73B – are ideal for mission‑critical IoT solutions, as they include a built‑in device and data security solution with a unique and immutable root‑of‑trust. With u‑blox CellLocate® cellular positioning technology, the device enjoys always and everywhere location awareness.

The SARA‑R4 modules are targeted to a wide range of data‑centric IoT applications, such as smart metering, smart lighting, telematics, asset tracking, remote monitoring, alarm panels, and connected health. The SARA‑R4 modules target long life, low‑maintenance, cost‑sensitive, lower power consumption, extended battery life applications.

The SARA form factor follows the u‑blox nested design principle and is compatible with other u‑blox product families, which facilitates easy migration from 2G, 3G and 4G. This also maximizes the investments of customers, simplifies logistics, and enables very short time‑to‑market.

The temperature range of –40 to +85 °C guarantees operation in harsh environments. The module is manufactured in ISO/TS 16949 certified sites with the highest production standards, quality and reliability. Each module is fully tested and inspected during production.
