Arduino Pro Mini 328 - 3.3V/8MHz [DEV-11114] - (AD2911)

Description:

It's blue! It's thin! It's the Arduino Pro Mini! Sparkfun's minimalist design approach for Arduino. This is a 3.3V Arduino running the 8MHz bootloader. The Arduino Pro Mini does not come with connectors, so you can solder any connector or cable in the orientation you need. We recommend that new Arduino users start with the Uno R3. It's a great tip that will help you get started quickly. The Arduino Pro series is for users who understand the system voltage limitations (3.3V), the lack of connectors, and off-board USB.

We really wanted to minimize the cost of an Arduino. In order to achieve this, we used all SMD components, two layers, etc. This board connects directly to the FTDI Breakout motherboard and supports auto-reset. The Arduino Pro Mini also works with the FTDI cable, but the FTDI cable does not have the DTR pin, so the auto-reset function will not work. There is a voltage regulator so it can accept voltage up to 12V DC. If you are supplying unregulated power to the board, be sure to connect to the "RAW" pin and not VCC.

NOTE: Connection pins are sold separately
