Arduino Pro Mini 168 - 5V/16MHz

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

It's blue! It's thin (0.8mm)! It's the Arduino Pro Mini! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader (select 'Arduino Diecimila' within the Arduino software). We added a handful of features to become a fully certified Arduino board.

Arduino Pro Mini 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 users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.

We really wanted to minimize the cost of an Arduino. The Arduino Pro Mini is like the Arduino Mini (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 Mini 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.

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

  • ATmega168 running at 16MHz with external resonator (0.5% tolerance)
  • USB connection off board
  • Supports auto-reset
  • 5V regulator
  • Reverse polarity protected
  • DC input 5V up to 12V
  • On board Power and Status LEDs* 0.7x1.3" (18x33mm)
  • Less than 2 grams

    This is a great product. It downloads perfectly with Arduino 0016 and I don't need to think in ISP and all these things.
    I would like to have its PCB print (like the Arduino shield boards) to put it in my projects. It would be nice to have this part inside your SFE library.
    Can you help me?

    Also having trouble uploading sketches to the pro mini 5V. I have been selecting the Arduino Diecimila and tried uploading from an old NG board (chip removed) and a 5V ftdi breakout, with no results. Is there some work around?

    • miles / about 15 years ago / 1

      ha ha, I have been using the 5V pro mini with the 128 chip previously. The new pro mini 5V I received has the 328 chip installed. So all I had to do was select Duemilanove w/328.

    Is it possible to use the 3.3v FTDI Basic board, unmodified, but instead of using the vcc pin on the FTDI board, simply supply the arduino pro mini with 5V from an alternative power supply? This would save you modifying the 3.3v FTDI board and leave it working for programming 3.3v versions of the Mini??

    Great implementation. Are there plans to rev this board with the Atmega328? How about a minimalist 128 implementation? I know I couldn't hold you to them, but timelines? Thanks!

  • TheCowGod / about 15 years ago / 1

    Answer: Yes, you do. I modified my FTDI basic breakout board for 5v as described in the comments, and now I can upload sketches to my 5v Arduino Pro Mini and receive Serial.println()'s back.

  • TheCowGod / about 15 years ago / 1

    I'm having trouble programming this with the FTDI 3.3v breakout board. Do I need to modify the FTDI board to run at 5v, as described in the comments for that product?
