• Manufacturer Part Number: WI.M900X-R
• Description: RF Modules & Development Tools 915 MHz RF MODULE Modu152kbit/s
• Manufacturer: Radiotronix

Specifications of WI.M900X-R

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant
• Other names: WIM900X-R

Typical Applications
Description
The Wi.M900X/T module is a
microcontroller-less version of our popular
Wi.232DTS module. It offers the same
excellent RF performance, yet allows the
design engineer to control the radio at the
physical level using any microcontroller.
The module is footprint compatible with the
Wi.232DTS module so upgrading to the
Wi.232DTS is very easy… no PCB changes
are required.
The module supports two modes of
operation: wide-band and narrow-band. In
wide-band mode, the channel width is
600kHz and in narrow-band mode the
channel width is 200kHz.
The module is configured via a simple SPI
style serial interface. Data is transmitted
and received using a separate digital serial
interface that includes pre-amble and start-
of-packet detection.
A typical circuit consists of a low-cost
microcontroller, a power source, a
Wi.M900X/T module, and an antenna.
The WiM900X module is a complete
transceiver while the WiM900T module is
transmit only. In addition, the modules can
be ordered for operation in the 868 MHz
band by substituting 868 for 900. For
example: WiM868X.
