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 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.
