The
Basic
Breakout Board has been specifically designed to add off board USB
connection to this module.
Description:
It's
blue! It's skinny! It's the Arduino Pro! SparkFun's minimal design approach
to Arduino. This is a 3.3V Arduino running the 8MHz bootloader (select
'LilyPad' within the Arduino software). The Arduino Pro is very much like
the Skinny, but we added a handful of features to become a fully certified
Arduino board. The power switch was moved to the side of the board (good
idea Limor!) to allow control when a shield is attached. This board does
not work with the 5V Arduino shields but does work nicely with our prototyping
shield.
Please
note: The right-angle power switch is fragile. We're working on making
the switch stronger. For now, please be gentle.
Arduino
Pro 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 Diecimila. 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
wanted Arduino Pro to be low profile. The DC power jack footprint is available,
but not populated. We recommend running the board with a LiPo battery for
better portability.
We
really wanted to minimize the cost of an Arduino. The Arduino Pro is like
the Arduino Diecimila (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
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.
The
Arduino Pro will slowly but surely be replacing the Skinny.

Additional
Notes from Sparkfun:
The
3V FTDI basic board is capable of bootloading the 5V Arduino Pro boards.
The only case where it becomes a problem is this:
-
The end
user attaches a bunch of external parts (servos, LEDs, sensors and
-
There
is no external power supplied.
The internal
3.3V regulator of the FTDI can only handle about 50mA before it starts
to sag. At 2V, the ATmega is not really capable of internally programming
the flash.
To
solve this, externally power the 5V board with 5V (the internal 3.3V reg
of the FTDI survives this without problems).
The
end user may also elect to purchase the 5V
cable from FTDI.
The
3.3V Version of the FTDI cable is listed here.
We
are tossing around the idea of a 5V version of the FTDI Basic Board but
we're not sure yet.
