Arduino UNO Compatible Prototyping Shield

** This works for more than just shields. They are a perfect to build your own Arduino UNO compatible boards, allowing for both top and bottom shields. The pins are aleady formatted to be UNO compatible!

Why can't the Arduino main board connect to a standard prototyping board (donut board)? That's because Arduino platform is designed with one header shifted 0.01 inch away from the standard 0.1 inch prototyping grid. Use the Proto Shield to get you out of the mess.

Cytron's Arduino Proto Shield is designed with two targets in mind – low cost & provide maximum prototyping area within Arduino's dimension. This product comes with 4 rows of stackable header and 4 SMD components - LED, push button, and resistor soldered on the well-labelled PCB. We ensure you that this is the lowest priced Arduino Proto Shield available in the market.
 
Also, take a look at the pin layouts. Notice that there are two rows where the pins have been shift back to the standard .02" prototype board standard spacing. This will allow you to install your own headers that you can use when building your own prototype boards. Now you can build your own shields to add above or below. Use this as a base to build your own Arduino board, build your own Arudino UNO shields, and now you can even add your own prototype boards without worry about the shifted pins.
 
All of this for less than $5. Compare this to other Arduino shields at $20 plus shipping!
