Arduino Pro 328 - 3.3V/8MHz

Description: This is the Arduino Pro - SparkFun's minimal design approach to Arduino. It is a 3.3V Arduino board running the 8MHz bootloader. The power switch was moved to the side of the board to allow control when a shield is attached. This Arduino board does not work with all Arduino shields because of the lower supply voltage.

Please note: Arduino 0015 supports the ATmega328 but not yet at 8MHz. Please select 'Arduino Duemilanove w/ 328' within the Arduino software but expect your delays to work twice as long (code will run half as fast as the Duemilanove at 16MHz).

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 Arduino Duemilanove. 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 (3.3V), lack of connectors, and USB off board.

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

SparkFun really wanted to minimize the cost of an Arduino. The Arduino Pro is like the Arduino Duemilanove (same pin out) but to keep the cost low, they 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.



  • ATmega328 running at 8MHz external resonator
  • Low-voltage board needs no interfacing circuitry to popular 3.3V devices and modules (GPS, Accelerometers, sensors, etc)
  • USB connection off board
  • 3.3V regulator
  • Max 150mA output
  • Over current protected
  • Reverse polarity protected
  • DC input 3.3V up to 12V
  • Resettable fuse prevents damage to board in case of short
  • Power select switch acts as on/off switch


Dimensions: 52,8 x 53,4 x 7,3 mm
