This baseplate holds an Arduino board (like the Uno or clones) and a self-adhesive breadboard. It comes with screws that give you a solid and simple connection.
An Arduino and a breadboard are not included. You must purchase them separately.
This plate can be used with any board that has the Arduino mounting holes. The Uno, the Mega R3, the Leonardo, the ADK R3, the Due, clones of them, or even similarly-shaped Arduino alternatives like the FEZ Panda can all be screwed down to the baseplate for easy prototyping. You can mount the board facing either way you like.
The following picture shows what it looks like when you have mounted an Arduino Uno and a solderless breadboard to this baseplate:
