Digi International's XBee SX 1 W, 900 MHz RF modules are the "muscle modules" of the 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. 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 and data reliability.

The XBee SX 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 XBee surface-mount form factor saves valuable board space.
