Cellular IoT Modules with Built-in GNSS Capabilities

10 February 2024

Supporting LTE-M cellular IoT transmissions, the SARA-R52 and LEXI-R52 wireless modules from u-blox both make use of the company’s UBX-R5 chipset, which it developed in house.

This enables a significant streamlining of communication system designs, avoiding the need for inclusion of additional external components. Of particular value is the fact that each has an integrated GNSS receiver. The proprietary SpotNow technology employed allows positioning to be determined to within a 10m margin (taking just a few seconds to get a precise fix). Both these modules support 23dBm output figures. The SARA-R52 has a 16mm x 26mm x 2.2mm size, while the LEXI-R52 maintains the same performance attributes but fits within 16mm x 16mm x 2mm dimensions. Up to 6 GPIOs are incorporated. They can fulfil a variety of use case scenarios - including metering, asset tracking, environment monitoring, etc.
