Digi XBee® SX 900 MHz RF modules are the “muscle modules” ofthe Digi XBee ecosystem, providing a combination of reliabilityand redundancy for OEMs building low-power, mission-criticalwireless devices. They utilize the DigiMesh® networkingprotocol, featuring redundant mesh network operation andsupport for low-power sleeping nodes. Customers that don’trequire mesh network architecture can configure the Digi XBeeSX 900 to operate in simple point to multipoint mode.With RF line-of-sight ranges up to 65 miles* and stronginterference blocking, these modules are ideal for applicationsrequiring the combination of range, data redundancy anddata reliability.The Digi XBee SX 900 modules can be configured easily usingDigi’s free XCTU software or via Digi’s simplified AT or APIcommand sets. They are pre-certified for use in multiplecountries and include integrated antennas, removing theburden of RF development/support costs and enabling fasttime to market for OEM designs. The modules provide secure, reliable delivery of critical databetween devices with 256-bit AES encryption, and the smallDigi XBee surface-mount form factor saves valuable boardspace.
