Notes:
• Minimum connections: VCC, GND, DOUT & DIN
• Minimum connections for updating firmware: VCC, GND, DIN, DOUT, RTS & DTR
• Signal Direction is specified with respect to the module
• Module includes a 50k pull-up resistor attached to RESET
• Several of the input pull-ups can be configured using the PR command
• Unused pins should be left disconnected
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 for
help in troubleshooting and building a robust design.
Power Supply 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, we recommend placing a 1.0 µF and
8.2 pF capacitor as near as possible to pin 1 on the XBee. If using a switching regulator for the
power supply, switching frequencies above 500 kHz are preferred. Power supply ripple should be
limited to a maximum 100 mV peak to peak.
