XBee 3 Module – PCB Antenna
First came the XBee 1 and 2 modules, and now we have this new series of modules with PCB antennas offering a host of features to open up more communication options.
XBee 3: an outdoor range exceeding 1 km
This module with its integrated antenna offers a transmit power of over 8 dBM at 40 mA. This means that 2 XBee modules with PCB antennas can communicate at a distance of up to 60 metres indoors, and over 1.2 km outdoors.
XBee 3 handles the 802.15.4 wireless communication protocol and the ZigBee 3.0 protocol. It is also BLE compatible and can communicate using a UART signal or SPI bus.
Programming the XBee 3 communication module
One great new feature of this series 3 module is that it includes a microcontroller programmable using MicroPython and XCTU. It is more usual to use XCTU for XBee 3 wireless communication configuration, so you are not required to use MicroPython to benefit from the module.
XBee 3 includes 15 digital input/output pins and four 10-bit ADC inputs. And it’s powerful enough to be used as a microcontroller if needed.
