XBee/XBee‐PRO DigiMesh 2.4 RF Modules
Pin Assignments for the XBee/XBee‐PRO 2.4 Modules
Design Notes:
The XBee modules do not specifically require any external circuitry or specific connections for proper operation.
However, there are some general design guidelines that are recommended to help with troubleshooting and building
a robust design.

* Function is not supported at the time of this release
Poor power supply design can lead to poor radio performance, especially if the supply voltage is not kept
within tolerance or is excessively noisy. To help reduce noise, we recommend that a 1.0 F capacitor and
an 8.2 pF capacitor be placed as near to pin1 on the PCB as possible. If you are using a switching regulator
for your power supply, switching frequencies above 500 kHz are preferable. Power supply ripple should be
limited to a maximum of 100 mV peak-to-peak.
The only required pin connections are VCC, GND, DOUT and DIN. To support serial firmware updates, also
connect RTS and DTR. All unused pins should be left disconnected. All inputs on the radio can be
pulled high with internal pull-up resistors using the PR software command. No specific treatment is needed
for unused outputs.
Other pins may be connected to external circuitry for convenience of operation, including the Associate LED
pin (pin15) and the commissioning button pin (pin20). The Associate LED will flash differently depending
on the state of the module, and a pushbutton attached to pin20 can enable various deployment and trou-
bleshooting functions without having to send UART commands.
The combined source and sink capabilities of the module are limited to 120 mA for all pins on the module.
Module pins 11 and 15 can source/sink a maximum of 2 mA; pins 9, 6 and 13 can source/sink a maximum
of 16 mA; all other pins can source/sink a maximum of 8 mA.
If analog sampling is desired, the VREF pin (pin14) should be attached to a voltage reference.
(Low‐asserted signals are distinguished with a horizontal line above signal name.)
