Overview

The SARA-R412M-02B is a versatile 4G LTE Cat M1 and NB-IoT cellular module designed for low-power wide-area (LPWA) networks. It uniquely includes quad-band 2G fallback capability, ensuring connectivity in regions where LTE coverage may be intermittent or unavailable. The module is housed in a compact 96-pin LGA castellation package, making it suitable for space-constrained industrial and consumer IoT applications.

Why Choose This Part

This module offers a maximum output power of 33dBm and supports a wide supply voltage range of 3.2V to 4.2V, facilitating direct battery operation. Its primary advantage is the integration of 2G GPRS/EGPRS fallback alongside modern Cat M1/NB-IoT, providing a future-proof path for transitioning legacy systems to LTE.

Applications

Global Asset Tracking
Utilizes 2G fallback to maintain connectivity while assets move between regions with varying cellular infrastructure.
Smart Utility Metering
Leverages NB-IoT for deep indoor penetration and long-term battery operation in water or gas meters.
Industrial Remote Monitoring
Provides reliable data transmission for sensors in remote locations using low-bandwidth LTE Cat M1 protocols.
