Snootlab I2C Power Protoshield V2 Kit

Second version of the protoshield - Arduino 1.0 pinout ready.

Designed for easy prototyping with Arduino (Arduino USB Board - Duemilanove, Uno, ... and Arduino Mega or Pro), this kit allows you to easily implement your projects.

The board has the exact dimensions of the Arduino Duemilanove and Uno to facilitate the installation of electronic projects; it features a soldering area that enables you to easily integrate the necessary additional components.

The stackable connectors connect all signals from the Arduino and make them available for your prototypes.

Two expansion slots are available:

* A Molex connector can connect your Arduino setup to a standard ATX PC power supply, allowing your Arduino to be easily self-powered.
* A HE10 connector for adding an I2C bus for communication with a large number of devices that support this format enables comprehensive communication for your Arduino.

An LED indicates the board status, and the reset button of the Arduino is accessible via the protoshield.

The board can also include a mini breadboard with 170 holes for temporary mounting.

Additionally, there is a 3.3V regulator that can be selected via a jumper on the protoshield and can provide more current than the Arduino. This feature is particularly interesting for many I2C devices.

For advanced users: When powered by an ATX PC, a box with chips can be used at 12V (when selected via the solder bridge under the protoshield). This allows you to control 12V devices, making it perfect for controlling transistor fans, motors, lamps, LED strips, relays, etc.
