Arduino Pro Mini 328 - 5V/16MHz

Retired Product

This is a retired product. There is an updated version available: DEV-11113

 Replacement: DEV-11113. The new version of the Pro Mini breaks out the ADC 6 and 7 pins! 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 Duemilanove w/ 328’ within the Arduino software). 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 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 (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.
