Refer to the Section 7.1 for details on each module pin and its function.  
 
The GPIO LEDs, Switches, Potentiometer and Thermistor are provided for demonstration 
purposes. These components can be read and written to using the ZBDemo program. The 
switches are momentary SPST switches and close to ground when pressed. The thermistor is 
used to vary an input voltage to the ADC X input with a maximum input voltage of 3.0 volts. 
Similarly, the potentiometer is connected in a resistor divider network to vary an input voltage to 
ADC Y input which can vary between ground and Vcc (~3.3V). Refer to the board schematics at 
the back of this manual for more details. To connect ADC X or ADC Y to off-board signals, 
disconnect the thermistor and potentiometer from the module inputs by removing JP3 for the 
potentiometer and JP4 for the thermistor. 
 
A group of four status LEDs are provided to allow board activity to be monitored. The LED 
functions are provided in the table below. 
 

Link 

On the Coordinator, illuminates when a clear channel has been detected and the 
Coordinator is ready for other devices to associate with it. 
On Routers and End Devices, illuminates when they have associated with a 
Coordinator. 

Activity 

Indicates RF data activity.
