The XBee RR 802.15.4 RF Modules are excellent embedded solutions. They offer wireless end - point connectivity to devices, using the IEEE 802.15.4 networking protocol for quick point - to - multipoint or peer - to - peer networking. Ideal for high - throughput applications that need low latency and predictable communication timing, these modules support low - cost, low - power wireless sensor networks. They use minimal power and ensure reliable data delivery. Operating in the ISM 2.4 GHz frequency band, they allow local configuration with BLE via the Digi XBee Mobile app. The XBee RR is similar to the XBee3 but lacks MicroPython and full BLE programmable services. The XBee line offers near plug - and - play wireless and mesh functionality for microcontroller projects, and the RR series enhances this. This is the PRO version of the RR module with an SMA Antenna connector (antenna sold separately). The PRO line gives more customization options but needs more configuration than standard XBee modules. Check the datasheet for full details.

Using the Digi XBee® RR Pro Module with SMA Antenna is easy. First, connect the antenna to the SMA connector (make sure to buy the antenna separately). Then, connect the module to your device according to the pinout diagram. You can use the Digi XBee Mobile app to configure it locally via BLE. For high - throughput applications, this module works great due to its low latency and predictable communication timing.
Here are some things to keep in mind. The PRO version needs more configuration than standard XBee modules, so be patient and refer to the datasheet. Make sure the operating temperature is between - 40 °C and 85 °C, and the supply voltage is between 1.72 V and 3.8 V.
For maintenance, keep the module clean and dry. If you want to upgrade the Bluetooth hardware to 5.0, wait for the future software release. When not in use, store the module in a safe place to avoid damage.
