Overview

The XB3-24AUM is a Digi XBee 3 module supporting the IEEE 802.15.4 protocol for high-performance wireless connectivity in the 2.4GHz band. It features a compact Micro form factor with a U.FL connector for external antenna flexibility, delivering up to 19dBm output power. The module integrates an HCS08 core with 1MB of Flash and 128kB of RAM, enabling on-board MicroPython programmability for edge intelligence.

Why Choose This Part

This module offers a significant power-to-size ratio with 19dBm output and -103dBm sensitivity for robust long-range links. The inclusion of 128kB RAM and 1MB Flash allows for complex local scripting, reducing the need for an external microcontroller in many IoT designs.

Applications

Smart End Nodes
Utilizing MicroPython to process sensor data locally and transmit via 802.15.4 to a central gateway.
Industrial Sensor Networks
Deploying low-latency point-to-point or star topologies in environments requiring external antennas for better signal propagation.
BLE Configuration Tools
Leveraging integrated Bluetooth Low Energy for local commissioning and diagnostics via the Digi XBee Mobile app.
