The XBee RR 802.15.4 RF Modules are excellent embedded solutions for wireless end - point connectivity. They use the IEEE 802.15.4 networking protocol, enabling fast point - to - multipoint or peer - to - peer networking. Ideal for high - throughput applications, these modules offer low latency and predictable communication timing. They're a great fit for low - cost, low - power wireless sensor networks, consuming minimal power and ensuring reliable data delivery. Operating in the ISM 2.4 GHz frequency band, you can configure them locally via BLE using the Digi XBee Mobile app. While functionally similar to the XBee3, it doesn't have MicroPython or the full BLE programmable services of the XBee3. The XBee line offers near - plug - and - play wireless and mesh functionality for microcontroller - based projects, and the RR series builds on this. This RR module comes with an SMA Antenna connector (antenna sold separately). Check the datasheet in the documents tab for full details.

Using the Digi XBee® RR Module with SMA Antenna is straightforward. First, make sure to connect the SMA antenna (which you need to buy separately) to the module. Then, power it up using a supply voltage between 1.72 and 3.8 V. You can configure the module locally via BLE using the Digi XBee Mobile app. For networking, it uses the Zigbee 3.0 protocol, enabling fast connections. When it comes to range, expect up to 90 m indoors or in urban areas and up to 3200 m outdoors in line - of - sight. As for Bluetooth, it supports BLE 4.2 as a slave and can work with some BLE 5.0 devices.
Here are some important notes. Keep the operating temperature between - 40 °C and 85 °C. Don't expose it to extreme conditions. Also, be aware that the transmit current is 195 mA at 19 dBm, so manage your power supply accordingly.
For maintenance, keep the module clean and dry. Avoid any physical damage to the SMA connector. If you face any issues, refer to the datasheet in the documents tab for more in - depth information.
