Digi XBee SX 900 RF Module

900 MHz OEM RF modules pack maximum power, security, and flexibility into the Digi XBee SMT footprint for mission-critical wireless designs

 
  • Family includes powerful 1-Watt 900 MHz Digi XBee-PRO SX 900 and battery-optimized 20 mW Digi XBee SX 900 modules for mission-critical OEM designs
  • DigiMesh networking topology for redundancy and reliability
  • Design includes SAW filter for optimal performance in noisy RF environments
  • 256-bit AES encryption for secure data communications
  • Digi XBee SMT form factor saves valuable PCB space
  • Fully certified for use in unlicensed 900 MHz band

Digi XBee® SX 900 MHz RF modules are the "muscle modules" of the Digi XBee ecosystem, providing a combination of reliability and redundancy for OEMs building low-power, mission-critical wireless devices. They utilize the DigiMesh® networking protocol, featuring redundant mesh network operation and support for low-power sleeping nodes. Customers that don’t require mesh network architecture can configure the Digi XBee 900 SX to operate in simple point to multipoint mode.

With RF line-of-sight ranges up to 65 miles* and strong interference blocking, these modules are ideal for applications requiring the combination of range, data redundancy, and data reliability.

The Digi XBee SX 900 modules can be configured easily using Digi’s free XCTU software or via Digi’s simplified AT or API command sets. They are pre-certified for use in multiple countries and include integrated antennas, removing the burden of RF development/support costs and enabling fast time to market for OEM designs.

The modules provide secure, reliable delivery of critical data between devices with 256-bit AES encryption, and the small Digi XBee surface-mount form factor saves valuable board space.

*30 dBm typical at 3.3 V and above. Maximum power will decrease at lower voltages.
**The device hops on 50 channels selected, using the CM command, from 101 available frequencies.
***We estimate rural ranges based on a 14.5 km (9 mi) range test with dipole antennas.
****Range estimated assuming that the urban noise floor is approximately 15 dB higher than rural. The actual range depends on the setup and level of interference in your location.
*****Range figure estimates are based on free-air terrain with limited sources of interference. Actual range will vary based on transmitting power, orientation of transmitter and receiver, height of transmitting antenna, height of receiving antenna, weather conditions, interference sources in the area, and terrain between receiver and transmitter, including indoor and outdoor structures such as walls, trees, buildings, hills, and mountains.
