LEXI-R422-01B

Feature-rich IoT connectivity in smallest form factor with 2G fallback

• Guaranteed best coverage with 23 dBm output power
• Cost-effective, power efficient, end-to-end IoT communication with MQTT Anywhere and MQTT Flex
• Always and everywhere location, with u-blox CellLocate®
• Better RF performance with configurable dynamic antenna tuning interface

LEXI-R422 is the first module of the u-blox LEXI 16 x 16 mm compact form factor. It offers LTE-M and NB-IoT coverage with 16 bands and software-based filtering configuration, plus 2G fallback to enable global deployments with a single product.

LEXI-R422 provides 23 dBm RF output power in LPWA bands, thus ensuring robust connections and lower rate repetitions especially at cell edges. It is more cost effective since no external power amplifiers are required to achieve best coverage.

The module’s dynamic antenna tuning interface optimizes the end-device antenna efficiency and overall RF performance. The antenna matching circuitry is tuned dynamically based on the frequency in use.
With PSM and eDRX, its low power consumption extends battery life to up to 10 years. LEXI-R422 has a dedicated interface to u-blox M10 modules, such as MIA-M10 (4.5 x 4.5 mm). As a pair, LEXI-R422 and MIA-M10 are at the core of ultra-compact, high performing tracking solution designs for applications requiring continuous tracking and flexible cellular and positioning power management. In additon, LEXI-R422 provides easy access to u-blox GNSS services AssistNow Online and Offline. It also allows easy access to u-blox’s CellLocate service to estimate position via surrounding cell station data without the need of a GNSS receiver.
With u-blox's MQTT Anywhere or MQTT Flex communication services, data overhead, time spent on-the-air, and energy consumption can be further reduced, thus enabling users to extend device life cycles, lower costs, and improve ROI.

Its many interface options and an integrated IP stack make LEXI-R422 perfect for a wide range of ultra-compact data-centric IoT applications, such as personal/pet trackers, telematics (ODBs), industrial automation and monitoring, smart city and smart building, payments, micromobility and connected health.
The LEXI-R422 leverages hardware-based security functions provisioned in a secured production environment, to ensure that the module only runs authorized firmware.
