XBee ZigBee Module

ZigBee’s mission is to cut the traditional wires between sensors, wired slave devices, and the microcontrollers and microprocessors they serve. Thus, if ZigBee is to emulate a wire, what goes in must come out without any significant change. MaxStream’s XBee ZigBee modules feature a UART interface, which allows any microcontroller or microprocessor to immediately use the services of the ZigBee protocol. All a ZigBee hardware designer has to do in this case is ensure that the host’s serial port logic levels are compatible with the XBee’s 2.8- to 3.4-V logic levels. The logic level conversion can be performed using either a standard RS- 232 IC or logic level translators such as the 74LVTH125 when the host is directly connected to the XBee UART.
