Arduino Pro Mini 328 - 3.3V/8MHz
Description: It’s blue! It’s thin! It’s the
Arduino Pro Mini! SparkFun’s minimal design approach to Arduino. This is
a 3.3V Arduino running the 8MHz bootloader. 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 (3.3V), lack of connectors,
and USB off board.
We really wanted to minimize the cost of an Arduino. In order to
accomplish this 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. There is a voltage regulator on board so it can accept
voltage up to 12VDC. If you’re supplying unregulated power to the board,
be sure to connect to the “RAW” pin on not VCC.
The latest and greatest version of this board breaks out the ADC6
and ADC7 pins as well as adds footprints for optional I2C pull-up
resistors! We also took the opportunity to slap it with the OSHW logo.
