Prime Intact Proto Shield (Prototype) for Arduino UNO with mini Breadboard Electronic Components Electronic Hobby Kit

Arduino UNO Prototype Shield is used in the cases where you want to build more applications without using any external Breadboard.The Prototyping Shield is designed to facilitate easy prototyping with an Arduino or an Arduino compatible board. It provides prototyping board space to build custom circuits and is great to build custom projects with the Arduino. All IO pins of the Arduino can be tapped into through header pins and empty solder pads for easy expansion. It works with UNO, Mega, Leonardo, NG, Diecimila, Duemilanove, and compatible Arduinos. Yun's and Arduino Ethernets have a chunky Ethernet jack that gets in the way of stacking, you can use the stacking headers included and it will work, just doesn't sit nice and flat.
