If you're trying to sink it, then your pin selection matters. If you're trying to source the current, yes.

Would I fry the chip by pulling 20ma through 14 of the I/O pins Note: A portion of this sale is given back to Arduino LLC to help fund continued development of new tools and new IDE features. 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.Ĭan't decide which Arduino is right for you? Arduino buying guide! If you're supplying unregulated power to the board, be sure to connect to the 'RAW' pin on not VCC. There is a voltage regulator on board so it can accept voltage up to 12VDC. 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.

This board connects directly to the FTDI Basic Breakout board and supports auto-reset. In order to accomplish this we used all SMD components, made it two layer, etc. We really wanted to minimize the cost of an Arduino. The Arduino Pro series is meant for users that understand the limitations of system voltage (3.3V), lack of connectors, and USB off board. It's a great board that will get you up and running quickly. We recommend first time Arduino users start with the Uno R3. Arduino Pro Mini does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. This is a 3.3V Arduino running the 8MHz bootloader.

It's blue! It's thin! It's the Arduino Pro Mini! SparkFun's minimal design approach to Arduino.
