Pin Assignments for the XBee‐PRO® 900 Modules
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 for
help in troubleshooting and building a robust design.
Poor power supply can lead to poor radio performance especially if the supply voltage is not kept
within tolerance or is excessively noisy. To help reduce noise a 1.0 uF and 8.2pF capacitor are
recommended to be placed as near to pin1 on the PCB as possible. If using a switching regulator
for your power supply, switching frequencies above 500kHz are preferred. Power supply ripple
should be limited to a maximum 100mV peak to peak. To ensure proper power up, Vcc SLOPE
must be superior or equal to 6V/ms.
The only required pin connections are VCC, GND, DOUT and DIN. To support serial firmware
updates, VCC, GND, DOUT, DIN, RTS, and DTR should be connected.
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 (pin 15) and the commissioning button pin (pin 20). The Associate LED pin will
flash differently depending on the state of the module, and a pushbutton attached to pin 20 can
enable various deployment and troubleshooting functions without having to send UART
commands.
The combined source and sink capabilities of the module are limited to 120mA for all pins on the
module. Module pins 11 and 15 can source/sink a maximum of 2mA; pins 9, 6, and 13 can source/
sink a maximum of 16mA; and all other pins can source/sink a maximum of 8mA.
If analog sampling is desired the VRef pin (pin 14) should be attached to a voltage reference.
XBee modules do not have any specific sensitivity to nearby processors, crystals or other PCB
components. Other than mechanical considerations, no special PCB placement is required for
integrating XBee radios. In general, Power and GND traces should be thicker than signal traces
and be able to comfortably support the maximum currents.
The radios are also designed to be self sufficient and work with the integrated and external
antennas without the need for additional ground planes on the host PCB. Large ground planes on a
host PCB should not adversely affect maximum range, but they may affect radiation patterns of
onboard XBee antennas.
