SparkFun will be closed Nov 26th and 27th for the Thanksgiving holiday. Orders placed after 2:00pm MT on the 25th will ship out Monday the 30th.
Description: It’s blue! It’s skinny! It’s the Arduino Pro! SparkFun’s minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader in a super-sleek form factor that will fit easily into your next small project.
Arduino Pro does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Uno R3. It’s a great board that will get you up and running quickly. The Arduino Pro series is meant for users that understand the limitations of this lack of connectors and USB off board.
To keep things affordable and low profile, we’ve chosen to make the DC power jack footprint available, but not to populate it. We recommend running the board with a LiPo battery for better portability. Also, to keep the cost low, we made changes like using all SMD components and switching to a two layer PCB.
This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work. In this latest version of the Arduino Pro we’ve also moved the FTDI headers back just a skoach so that the pins don’t hang over the edge of the board. We’ve also populated it with a sturdier power selection switch.

We have included 40-50 Pro 328s in a product we provide to a niche market, too small to be worth making our own board, but one with significant revenue, primarily resulting from the included software.
We have only had a couple of failures of the Pro 328. We did not even troubleshoot as the boards are so cheap it’s not worth the effort.
We are developing another product employing the Pro 328 as Sparkfun as not indicated any plan top discontinue production. Should that happen we hope to have enough overall volume established to make it worthwhile for us to build our own should it become necessary.
On the other hand, as long as they keep building the board we are very happy sourcing from Sparkfun.
