GPIO Specifications

XBee RF modules have 15 GPIO (General Purpose Input / Output) ports available. The exact list will depend

on the module configuration, as some GPIO pads are used for purposes such as serial communication.

See GPIO section for more information on configuring and using GPIO ports.
