Gravity: IO Expansion Shield for Arduino V7.1(DFR0265)
INTRODUCTION
IO Expansion shield is one of the market favourites. Fast robotics
prototyping made affordable and simple thanks to this design. Soldering
and wiring often becomes a problem when a bridged connection happens and
components break. Increasing time a costs for projects. Often, without
this solution and a soldering station, wire cripping tools or soldering
station, robot prototyping or electronics DIY becomes a very long term
project.
The DFRobot Expansion shield introduced to the market the famous color
code for sensors and actuators input and output. The 3 pin format for
Signal, Voltage and Ground is extremely useful, specially 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.
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.
