Arduino Pro 328 - 5V/16MHz

It's blue! It's skinny! It's the Arduino Pro 328! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software). The power switch was moved to the side of the Arduino Pro 328 board (good idea Limor!) to allow control when a shield is attached.

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

Arduino Pro 328 microcontroller does not come with connectors populated so you can solder in any connector or wire with any orientation you need providing more flexibility. 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 recommend first time Arduino users start with the Uno. It's a great board that will get you up and running quickly.

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.

Features of the Arduino Pro 328 - 5V/16MHz:

  • ATmega328 running at 16MHz external resonator. Select 'Arduino Duemilanove w/ 328' to get the delay functions to work correctly.
  • USB connection off board
  • 5V regulator
  • Max 150mA output
  • Over current protected
  • 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

Arduino Pro 328 - 5V/16MHz Dimensions: 2.1x2.05" (53.34x52.08mm)
