Need space to add custom circuits to your Arduino MEGA? Here's the open proto shield!
This is just the PCB for building the MEGA Protoshield
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.
This PICAXE-28X2 module contains a surface-mount 28X2 chip, voltage regulator, download socket, and reset switch in a convenient 28 pin (0.6") format. Ideal for breadboarding work.
The PICAXE USB programmer allows PICAXE micros to be programmed from any platform (Windows and Linux).
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!&#
