Description

It's blue! It's skinny! It's the Arduino Pro! SparkFun's minimal design approach to Arduino. This is a 3.3V Arduino running the 8MHz bootloader. Because the system voltage for this board is lower than other Arduino development boards, it may not be compatible with many Arduino shields which were designed to run at 5V. The Arduino Pro 3.3V still works great with our prototyping shield so you can create your own 3.3V shields. The lower system voltage also has its advantages, like ease of use with many common 3.3V sensors.

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 Uno R3. 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 (3.3V), lack of connectors, and USB off board.

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.

Product review & video

good morning all I'm looking at my arduino pro mini collection I have all nine of these things because I'm looking to shrink if I know not shrink if I miniaturized my Arduino hygrometer this is my Arduino humidity indicator I've made a few changes to the software it now indicates humidity in big numbers with a percentage sign and temperature in small numbers with a degrees C after it and this is the device that uses this si 702 one humidity sensor chip now I should just mention if you're following this project that the level translatable this one here that I put between the Arduino and the sensor board is completely unnecessary in fact I'm amazed it still works because those level translation components which are two MOSFETs a bunch of resistors and also the five volt to three volt 3.3 volt regulator are actually on the back of this sense Borden it I didn't wake up to that fact there's
