3. Functional Description
The radio modules contain the RF transceiver, a 50  matching circuit for the 915/868 MHz*, the necessary
external components (quartz crystal, power supply decoupling capacitors, etc.) and a small spiral antenna.
The module also contains a microcontroller for configuring and controlling the radio. The power, programming pins
and some of the available I/O connections are available via the connector and routed to the peripheral board for
easy access.
*Note: In order to operate at 434 MHz, matching network values are published on the schematics (See Figure 9, “EZLink Radio
The peripheral board is designed to provide access to commonly used interfaces such as battery, USB, and debug
connections. For prototyping purposes the peripheral board also has LEDs, a push button, and test points. To help
with the module orientation, the module’s connector is keyed and the silkscreen has a white triangle to point to the
antenna end.
Note: The white triangle is used to denote the correct orientation of the module and the peripheral board.
