1.XBee®/XBee‐PRO®RFModules
The XBee and XBee-PRO RF Modules were engineered to
meet IEEE 802.15.4 standards and support the unique
needs of low-cost, low-power wireless sensor networks.
The modules require minimal power and provide reliable
delivery of data between devices.
The modules operate within the ISM 2.4 GHz frequency
band and are pin-for-pin compatible with each other.
