Pro Micro - 3.3V/8MHz

Here at SparkFun, we refuse to leave 'good enough' alone.
That's why we're adding to our line-up of Arduino-compatible microcontrollers once more!
The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board.
The USB transceiver inside the 32U4 allows us to add USB connectivity on-board and do away with bulky external USB interface.

This tiny little board does all of the neat-o Arduino tricks that you're familiar with:
4 channels of 10-bit ADC, 5 PWM pins, 12 DIOs as well as hardware serial connections Rx and Tx.
Running at 8MHz and 3.3V, this board will remind you a lot of your other favorite Arduino-compatible boards but this little guy can go just about anywhere.

This is the 3.3V version so, as always, keep in mind the limits of system voltage and so forth.
The lower system voltage also has its advantages, though, like ease of use with many common 3.3V sensors.

Not sure which Arduino or Arduino-compatible board is right for you?

Note: As of September 17, 2012 these boards will be shipping with a new version
of the Caterina bootloader developed by Arduino for the Leonardo, which incorporates
a couple of bug fixes and enhancements. First, the code has been modified to compile differently for 8 and 16MHz systems.

Most significantly, though, the behavior of the bootloader on reset has been changed.
By default, the Caterina bootloader remains in bootloader mode for 8 seconds after an external reset,
to allow the user a chance to upload code should the previously uploaded code disable the USB functionality.
We found that to be excessive when resetting the device during program development,
so we replaced that with a "double tap" function.
To override the main code and stay in the bootloader for 8 seconds,
press the reset button twice in quick succession.
