XBee and XBee PRO DigiMesh 2.4 OEM RF Modules

The XBee/XBee-PRO DigiMesh 2.4 OEM RF Modules were engineered to support the unique needs of low-cost, low-power wireless sensor networks. The modules require minimal power and provide reliable delivery of data between remote devices.

The XBee modules us the ISM (Industrial, Scientific & Medical) 2.4 GHz frequency band

Serial communications:

The XBee/XBee-PRO 2.4 DigiMesh OEM RF Modules interface to a host device through a logic-level asynchronous serial port. Through its serial port, the module can communicate with any logic and voltage compatible UART; or through a level translator to any serial device (For example: Through a Digi proprietary RS-232 or USB interface board).
