XBee USB Adapter Board (#32400)
This low cost XBee USB Adapter Board comes in partially assembled kit form and provides a cost-effective
solution to interfacing a PC or microcontroller to any XBee or XBee Pro module. By using this adapter
board you can provide an easy interface to the XBee or XBee Pro modules by converting the 2mm pin
spacing to breadboard friendly 0.100” spacing. The adapter boards also provide a means to connect
pluggable wires or solder connections and also provide mounting holes.
Features
Provides an easy interface for configuring an XBee Module via a PC
4 status indicator LEDs for Power, RSSI, Associate and mode (sleep/ON)
Converts XBee 2mm pin spacing to 0.100” pin spacing
Provides easy pluggable wire or solder connections
Includes mounting holes
Pin-out compatible with our other XBee Adapter boards
Partially assembled kit form for flexible configuration
Key Specifications
Power requirements: 3.3V pass-through to XBee module
Communication: Serial pass-through to XBee module
Operating temperature: -40 to +158°F (-40 to +70°C)
Dimensions: 1.51” L x 1.00” W x 0.58” H* (38.3 mm x 25.6 mm x 14.8 mm*)
* when headers are attached
Application Ideas
Easy connection of XBee modules to PC for configuration
Easy connection of XBee modules to breadboard or proto board
Convenient way to mount the XBee module away from the microcontroller

Assembly Instructions
Step 1:
Check to ensure your kit
contains the following parts
as shown in the photo.
Step 2:
Install the 2mm sockets on
top of the PCB as shown and
solder them in place from the
bottom side of the board.

Step 3:
Using an Exacto knife,
hobby knife or a pair of
diagonal cutters, cut two 11pin headers from the 40-pin
header. Extra header
material was included in
case of a mistake or
damaged header.
Step 4 (optional):
Insert the two 11-pin SIP
headers into the bottom of
the adapter board as shown
and solder them in place
from the top.
This step is optional in that
you could leave the headers
out and solder wires into the
pads instead if you wish.
Headers are also not needed
for PC communication or
power since both are
obtained from the USB port.

USB Driver Installation
If you wish to connect your XBee USB Adapter to your PC then you will first need a USB A to Mini B cable
(sold separately). You will also need to install the FTDI VCP drivers. You may obtain the latest drivers by
pointing your web browser to http://www.parallax.com/usbdrivers. You may also obtain these drivers
from the FTDI website at http://www.ftdichip.com/Drivers/VCP.htm. Note: you may already have the
USB drivers installed if you have installed the Propeller Tool software or use any Parallax USB
development boards.
Once the USB driver has been installed you may connect your USB cable between the PC and the XBee
USB Adapter Board. The XBee USB Adapter is now ready to be configured via the X-CTU software from
Digi. Note that the functions of some of the I/O lines on the adapter can be configured from the X-CTU
software. As long as the USB port is providing power the XBee Adapter Board is powered on. Please
remember that the I/O signals are 3.3V level and should not be connected to a 5V system without proper
buffering. The XBee I/O pins are not 5V tolerant.
Connecting and Testing
Connect your compatible microcontroller to the required pins on the XBee USB Adapter. The VDD pin will
be at 5V whenever the USB port is providing 5V. The VCC pin will be at 3.3V but if you’re powering from
USB you won’t want to draw more than ~40mA from this pin.
If you need to power your XBee Module in the absence of USB power you can connect a regulated 5V
supply to the VDD pin and the FTDI USB chip and the XBee Module will be powered. Do not connect
voltage to the VDD pin when the USB cable has power or you may damage your PC and/or
your XBee Module.
LED Status Indicators
The XBee USB Adapter has 4 LEDs for status indication. Whenever the board has 5V from either the USB
or external power to VDD the Yellow LED lights up. The Green LED indicates the module is ON (not in
standby mode). The Blue LED is connected to the RSSI pin and the Red LED is connected to the
Associate pin. Some of these functions can be reconfigured using the X-CTU software.
LED FUNCTIONS:
Yellow – Power
Green – ON (Not in standby mode)
Blue – RSSI
Red – Associate
The USB connector also has two LEDs which indicate TX / RX status. The Red LED indicates data being
transmitted to the PC and the Green LED indicates data being received from the PC.
