Gravity: IO Expansion Shield for Arduino V7.1

The DFRobot Expansion shield introduced to the market the famous colour code for sensors and actuators input and output. The 3 pin format for Signal, Voltage and Ground is extremely useful, especially if used altogether with our increasingly large range of modules, sensors and devices that just fit. 

Alternatively, the board includes power input for salvaged power supplies or laboratory power supplies. Very common Xbee socket for multipurpose wireless connectivity such as RF, wireless, Bluetooth. 

The new version includes a voltage hardware setting through a jumper to allow compatibility with a bigger range of components at 3.3v like Raspberry pi, Due and others.

It also includes a Servo external power, with a protective diode. This way you can enable a large range of servos from your Arduino.

The latest version features a convenient switch that lets you program your ATmega328 boards like UNO, while you have another Serial device connected like a Xbee. Switch it, program it and get it back up and running with another switch. You don't need to disassemble your hardware or wiring.

A LED on top board and a reset button is in order to make it just a natural extension to Arduino boards. The LED is connected to pin 13.
