Digi XBee 3 - LTE-M/NB-IoT/GNSS module

Description

The Digi XBee 3 module is a modern, compact solution designed for quick integration of IoT capabilities using a cellular network. It is equipped with cellular and BLE connectivity and was created to enable the creation of secure wireless devices with global access and positioning capabilities. Combining the XBee ecosystem with cellular functionality creates a simple system for working with data via a cellular connection.

LTE-M and NB-IoT cellular standards are optimized for low energy consumption and transmitting small amounts of data, such as asset tracking or smart sensors (less than 5 MB of data per month). A global connection is instantly available with Digi XBee 3 global cellular. This module offers an excellent power saving mode, extending battery life and operating time. It does not come with a SIM card. To make IoT development easier, the XBee 3 suite includes a range of MicroPython development resources, the intuitive XBee Studio tool, and a 12-month Digi Remote Manager subscription for each module, enabling remote software updates and monitoring. Digi XBee Studio, a powerful tool designed to accelerate development, production and deployment, further facilitates IoT deployment in cellular networks.
