This is a protoboard that stacks on to the Arduino UNO – It brings all the data, I/O 5V and Ground pins to the shield and provides a nice surface for soldering your components. Stacking headers are included so you can stack additional shields onto this one.
In addition to the protoboard surface, this shield also comes complete with 2 general purpose push button switches and 2 general purpose red LEDs. It also has a solder pads for a 14-Pin SOIC SMD IC.
The shield comes with a mini solderless breadboard adhered in the prototyping area. Turn your Arduino into a true prototyping platform. This item is just the Arduino Uno Prototype Shield with a Breadboard.
