Confidential
The modules support multi-band data communication over an extended operating temperature range
of –40 to +85 °C, with extremely low power consumption, and with coverage enhancement for deeper
range into buildings and basements (and underground with NB2).
SARA-R5 series modules include the following variants / product versions:
SARA-R500S LTE Cat M1 / NB2 module for multi-region use, cost effective solution for devices
that do not need to reach ultra-low power consumption in deep-sleep power saving mode (PSM)
SARA-R510S LTE Cat M1 / NB2 module for multi-region use, designed to achieve extremely low
current consumption in deep-sleep power saving mode (PSM)
SARA-R510M8S LTE Cat M1 / NB2 module for multi-region use, integrating the u-blox M8 GNSS
receiver for global position acquisition
Table 2 summarizes cellular and GNSS characteristics of the modules.
