XBee Pulse I/O Breadboard or Perfboard Assembly Instructions
We're going to lead you through step-by-step instructions to build a prototype XBee Pulse
I/O board on a breadboard. This board can be used to automate many things around a home
and control them remotely. This design is featured in Make Vol. 30 and is used to connect a
garage door opener to a mobile phone.
Step 1 — XBee Pulse I/O Breadboard or Perfboard Assembly Instructions
Assembly begins with the power circuit.
Place the 0.1uF capacitor C8 between the input pin (pin 3) of the 3.3v power regulator VR1
(datasheet) and ground. If you look closely the capacitor has a little "104" written on it.
Place the 10uF capacitor C9 between the output pin (pin 2) of the regulator and ground.
Take care to orient the negative pin of the capacitor to ground.
Connect the ground pin (pin 1) of the voltage regulator to ground.
Tie the output pin (pin 3) of the power regulator to one of the breadboard's power rails so
you’ll have easy access to clean 3.3v power when you put in the other components.

Step 2
Assembly continues by creating the circuit for the XBee. Set aside your XBee module for
now; we'll use it later.
You may insert the XBee breakout board now--note that if you ordered your board from
SparkFun you'll have to solder the headers on. You may find as you work you'll add and
remove the breakout board to give yourself some space, don't sweat it!
Connect capacitor C4 (10pF) to ground. If you look closely, it will have a little "100" written
on it. Connect the other side of C4 to the XBee breakout board's pin 1.
Continue by also connecting pin 1 of the XBee breakout board to your clean 3.3v power
rail.
Connect pin 10 of the XBee breakout board to ground.

Step 3
Continue by attaching the LED to pin 15 of the XBee, the other pin of the LED to the 180Ω
resistor R5 (brown, grey, brown, gold) and the remaining pin of the resistor to ground.
Take care to orient the LED correctly! The long leg of the LED is the anode
(positive) and should be connected to the XBee's pin 15.
This LED will act as our association light and let us know that we’re connected to our
wireless network.

Step 4
Next, connect up the momentary pushbutton switch S1 by connecting it to pin 20 of the
XBee.
Connect the other side of the switch to ground.
This switch is our network commissioning button and will let us easily associate and test
our XBee’s connection to our network.
