This is just the PCB for building the MEGA Protoshield
For when you need to make your own stuff to stick on an Arduino-sized outline!
This board mates directly with the Arduino USB board and allows the Arduino to wirelessly communicate over a modified ZigBee protocol using the popular XBee module from MaxStream.
Sometimes a gentle "beep" and "boop" isn't enough from a microcontroller. The Adafruit Wave Shield adds these audio capabilities to your Freeduino SB / Arduino!
Intertoobs. Intarwebs. Series of tubes. Whatever. Connect your Arduino / Freeduino SB to your LAN, WAN, or whole darn Internet!
The Sparkfun Arduino protoshield as some very useful portable prototyping space that plugs onto the top of the popular Arduino / Freeduino SB.
