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.

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

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.
My go-to board for small projects. Works great, never fails. Cheap!
I used this board in some custom built test hardware for our sensor. It’s used conjunction with a CAN shield. I’ve built about 10 of my test boxes so far and distributed them to customers all over. Sure, we can build our own circuit boards, and write complex code from scratch, but this saves us a ton of time. I think sparkfun would be proud to know that one of the top OEM automotive suppliers in the world is using their boards!
Thanks, we’re always proud and happy to learn about the millions of ways people are coming up with to use our products!
