Digi International XBee3 2.4GHz ZigBee 3.0 Module w/ PCB Antenna

Use the free Digi International XCTU software to configure the XBee3. Connect the module via a USB-to-UART adapter to your computer, launch XCTU, and detect the module. You can then set the network parameters like PAN ID, destination address, and security keys using AT commands or the API frame structure. For ZigBee 3.0, ensure the firmware profile is set to 'ZigBee 3.0' and configure the device as a Coordinator, Router, or End Device as required by your network topology.

Yes, the XBee3 has a built-in MicroPython interpreter, allowing you to write and run Python scripts directly on the module. After enabling MicroPython mode in XCTU, you can upload .py files to the module's flash memory. Your script can then control the GPIO pins, read ADC values, manage wireless communication, and implement application logic autonomously, eliminating the need for a separate host MCU in many edge node designs.

The XBee3 consumes 40 mA during transmission at +8 dBm and 15 mA while receiving. For battery operation, utilize its sleep modes. Configure sleep settings (e.g., SM parameter) via AT commands to put the module into periodic or pin-controlled sleep. In the deepest sleep (power-down) mode, current drops to 1.7 µA. Ensure your host system or MicroPython script manages the SLEEP_RQ/DIO9 pin and wake-up intervals correctly to maximize battery life in remote sensor applications.

The primary interface is a UART (configurable baud rate up to 1 Mbps) for AT commands, API data frames, and MicroPython REPL. The SPI and I2C interfaces are enabled via specific DIO pin configurations and are typically used when the XBee3 acts as a peripheral to a host processor for high-speed data transfer or to connect external sensors. You must configure the relevant DIO pins to the appropriate alternate function (SPI_MOSI, SCL, etc.) using AT commands or within your MicroPython script before using these interfaces.
