XBee RR 802.15.4 RF Modules are embedded solutions providing wireless end-point connectivity to devices. These devices use the IEEE 802.15.4 networking protocol for fast point-to-multipoint or peer-to-peer networking. They are designed for high-throughput applications requiring low latency and predictable communication timing. The XBee RR 802.15.4 RF Module supports the needs of low-cost, low-power wireless sensor networks. The devices require minimal power and provide reliable delivery of data between devices. The devices operate within the ISM 2.4 GHz frequency band. It allows local configuration with BLE using the Digi XBee Mobile app. The XBee RR is functionally equivalent to the XBee3 but does not offer the MicroPython nor the full BLE programmable services offered by the XBee3.
The XBee line provides the closest to plug and play wireless and mesh functionality of all the wireless products we sell for microcontroller based projects. The RR series continues to build on that.
This variation of the RR module is fitted with a U.FL Antenna connector (antenna sold separately). For full information on the module, check out the datasheet in the documents tab.

Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- u.FL
- u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
- Zigbee
- A low-power wireless standard commonly used by smart home sensors, switches, and lights. It matters if you want the board to communicate with Zigbee devices or act as part of a home automation network.
