u-bloxLEXI-R520-02B
Overview
The LEXI-R520-02B is an ultra-compact LTE Cat M1 and NB2 cellular module featuring an integrated GNSS receiver in a 16 x 16 mm LGA package. It provides global multi-band connectivity with extremely low power consumption, including a 0.5 uA deep-sleep mode, making it ideal for battery-operated IoT devices. The module supports a wide supply voltage range from 3.3V to 4.4V and includes comprehensive protocol support for MQTT, HTTP, and TLS security.
Why Choose This Part
The module offers a unique combination of dual-mode LTE Cat M1/NB2 and GNSS in a miniature form factor that reduces PCB area compared to multi-chip solutions. Its 0.5 uA shutdown current and Power Saving Mode (PSM) significantly extend the battery life of remote nodes. Engineers benefit from the extensive u-blox ecosystem, including AssistNow for fast GNSS time-to-first-fix and uFOTA for secure over-the-air firmware updates.
Applications
Key Specifications
Getting Started
To evaluate the module, use the u-blox EVK-LEXI-R5 evaluation kit which provides breakout access to the UART interfaces and antenna connectors. Development is typically performed using AT commands or the u-blox m-center software tool for configuration and network testing. Ensure proper thermal management for the 133-pin LGA package and follow the recommended layout for the 50-ohm RF traces to the external antennas.
