Arduino Pro 328, 5V, 16MHz – SparkFun DEV-10915

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 the 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, Sparkfun also moved the FTDI headers back just a wee bit so that the pins don’t hang over the edge of the board. To ensure longevity they also populated it with a sturdier power selection switch.
