The Arduino Pro 328 - 5V/16Mhz microcontroller board is a minimal version of the Arduino by SparkFun designed for the experienced user who wants control over how connections are made to the board and a low cost. The Arduino Pro uses the same ATMega chip as the Arduino Duemilanove 328 USB Board.
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 and with the same ATmega328 chip as the Arduino Duemilanove USB 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. SparkFun are 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 Duemilanove. It's a great board that will get you up and running quickly and is more suited to experimentation. The Arduino Pro series is meant for advanced users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.
SparkFun 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.
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.
Note: When using the Arduino software select 'Arduino Duemilanove w/ 328' as the board.
ATmega328 running at 16MHz external resonator. Select 'Arduino Duemilanove w/ 328' to get the delay functions to work correctly.
