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.
16.000MHz. That's pretty darn precise. And exactly the value needed to run an ATmega8/168/328 microcontroller at Arduino-compatible frequency!
2.1mm barrel power jack socket. For connecting barrels, I mean "power leads"!
The ScrewShield is a “wing-format” shield that extends the Arduino pins to sturdy, secure, and dependable screw terminal blocks. (You even get a few bonus terminals for extra GND and power!&#
