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!&#
This is the SparkFun basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and compatible (like the Freeduino SB) boards. 3.3V version.
This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards.
