Retired RETIRED

This product has been retired from our catalog and is no longer for sale.

This page is made available for those looking for datasheets and the simply curious. Please refer to the description to see if a replacement part is available.

Replacement: DEV-09219 and DEV-09221. This has been replaced with a new version with the ATmega328. This page is for reference only.

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 (select 'Arduino Diecimila' within the Arduino software). The Arduino Pro is very much like the Skinny, but we added a handful of features to become a fully certified Arduino board. The power switch was moved to the side of the board (good idea Limor!) to allow control when a shield is attached.

Please note: The right-angle power switch is fragile. We're working on making the switch stronger. For now, please be gentle.

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 Diecimila. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for advanced users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.

We wanted Arduino Pro to be low profile. The DC power jack footprint is available, but not populated. We recommend running the board with a LiPo battery for better portability.

We really wanted to minimize the cost of an Arduino. The Arduino Pro is like the Arduino Diecimila (same pin out) but to keep the cost low, we used all SMD components, made it two layer, etc. 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.

The Arduino Pro will slowly but surely be replacing the Skinny.

Note: A portion of this sale is given back to Arduino LLC to help fund continued development of new tools and new IDE features.

Features:

  • ATmega168 running at 16MHz external resonator. Select 'Arduino Diecimila' board to get the delay functions to work correctly.
  • USB connection off board
  • 5V regulator
  • Reverse polarity protected
  • DC input 5V up to 12V
  • Resettable fuse prevents damage to board in case of short
  • Power select switch acts as on/off switch

  • Wonder when are you going to have the FTDI cable or board in existence in order to buy one of this awesome devices

  • Mmmm.. Its hard to see it’s 5V from the schematic, all the power is labeled 3V3.

    • Schematic is fixed. Thanks for letting us know.

    • I agree. The schematic is confusing. Also, the “Arduino Pro Homepage” link is all 3.3v. This really needs to be clarified before I would order this board. Also, the Pro and Pro Mini have an on-board voltage regulator. How much current can it supply? Could I power a 5v peripheral from the Pro (pro mini) board?

  • Would this board be reccomended over the Duemilenove for projects such as POV displays and portable projects?

  • Now that it runs on 5V, does that mean it can’t run from a single LiPo cell anymore?

  • Awesome!!!
