Although the Arduino boards have been regarded as one of the costless boards, however it’s still need a sum of money out from your pocket, especially if you’re purchase in large amount! You must be wondered, “Is there any cheaper, skinnier, and more stylish Arduino board around the market?” Well, since you’ve asked for it, then you got it…

Today, you’ll have the chance to look at the new and sophisticated blue Arduino Pro board. This Arduino Pro appearance is just like the Arduino Diecimila, but it used all SMD components to make it becoming a two layer. By this way, the board can be directly connected to the FTDI Basic Breakout board and supports the auto-reset. Furthermore, the Arduino Pro can also work with the FTDI cable, but you must careful as the FTDI cable doest not bring out the DTR pin.

Since the Arduino Pro’s designation is very much like the Skinny, most of the people will have the wrong thoughts that it is a Skinny! However, you can easily differential it as the power switch was moved to the side of the board to allow a better control when a shield is attached on it!

One thing you should pay attention with this Arduino Pro is the right-angle power switch is fragile than the other components. Therefore, you should be gentle with it! Schematic and Eagle Files.
