Description The XBee-PRO 900 RF module is ideally suited for less power-hungry, low-latency point-to-multipoint networking applications. Capable of point-to-point, peer-to-peer and point-to-multipoint networking, The XBee-900 modules have a higher selectable transmitting power of 250mW. This higher Tx power allows for line-of-sight range up to 28 miles with the right antenna. It is ideal for solutions where RF penetration and absolute transmission distance are paramount to the application. As a member of the XBee family of RF products, the module is easy-to-use, shares a common footprint, and leverages Digi’s Drop-in Networking solutions including gateways and adapters. No configuration is necessary for out-of-the-box RF communications. The module’s default configuration supports a wide range of data system applications. Advanced configurations can be implemented using simple serial AT commands. 900MHz VS 2.4GHz Most of the Xbee modules operate at 2.4GHz, but there are a few that operate at 900MHz. Basically, 900MHz can go a lot farther with a high gain antenna (up to 15miles for the Pro modules and a high gain antenna). Also the lower the frequency the greater penetration the signal has. 900MHz is also not allowed in many countries (although there are 868MHz versions available from Digi that are allowed in many other countries). You can NOT mix and match these on the same network. Hardware Processor: ADF transceiver, Cortex-M3 EFM32G MHz Programmable includes: Freescale MC9S08QE32 Frequency Band： 902 to 928 MHz, software selectable channel mask for interference immunity Performance RF Data Rate： 10 Kbps or 200 Kbps Indoor/Urban Range： 10 Kbps: up to ft (610 m); 200 Kbps: up to ft (305 m) Outdoor/ Line-Of-Sight Range： 10 Kbps: up to 9 miles (14 km); 200 Kbps: up to 4 miles (6.5 km) (w/ 2.1 dB dipole antennas) Transmit Power： Up to 24 dBm (250 mW) software selectable Receiver Sensitivity： -101 dBm @ 200 Kbps, -110 dBm @ 10 Kbps Features Data Interface： UART (3V), SPI GPIO： Up to 15 Digital I/O, 4 10-bit ADC inputs, 2 PWM outputs Networking Topologies： DigiMesh, Repeater, Point-to-Point, Point-to-Multipoint, Peer-to-Peer Spread Spectrum： FHSS (Software Selectable Channels) Programmability Memory： N/A 32 KB CPU/Clock Speed： N/A Power Supply Voltage 2.1 to 3.6 VDC C Transmit Current 215 mA Receive Current 29 mA Sleep Current 2.5 uA Physical Properties Weight: 6.4g Size: 3.3cm x 2.5cm (4.5 x 2.5cm with connector) Antenna： RPSMA Package list: 1 x XBee PRO S3B RPSMA antenna" Box Pack - No Warranty
