The Wireless Proto shield allows an Arduino board to communicate wirelessly using a wireless module. It is based on the Xbee modules from Digi, but can use any module with the same footprint.
The module can communicate up to 30 m. indoors or 90 m. outdoors (with line-of-sight). It can be used as a serial/usb replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options. The shields breaks out each of the Xbee's pins to a through-hole solder pad.
This shield doesn't have the SD socket.
An on-board switch allows the wireless module to communicate with the USB-to-serial converter or with the microcontroller.
