ARDUINO PROMINI 328 5V16MHZ

It's the Enhancement V2 Pro Mini! It's thin (0.8mm)!This Mini board with a adjustable voltage regulator(you can setting the output voltage by yourself) running the 16MHz bootloader ((select 'Arduino Duemilanove w 328' within the Arduino software). This Pro Mini V2 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 Enhancement V2 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 Enhancement V2 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.
