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
SX 900 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.
