Arduino A000064/65 Wireless Proto Shields allow an Arduino board to easily connect with an RF Module, enabling wireless communication using external wireless modules. They are based on the Xbee® ZigBee® RF modules from Digi, but can use any Wireless module with the same footprint as XBee modules. Proto shield-connected modules can be used as serial/USB replacements or they can be put into command mode and configured for a variety of broadcast and mesh networking options. The shields break out each Xbee RF module pin to a through-hole solder pad for easy access. The A000064 comes without SD slot, while the A000065 does include an on-board SD card slot. Both shields include a switch allowing for control via USB or the microcontroller.
