SparkFun Pro Micro - 5V/16MHz Feather

SparkFun Pro Micro - 5V/16MHz FeatherHere 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: 9 channels of 10

Tracks can be controlled via 16 programmable trigger inputs

and there are some bugs still being found and fixed

This unit works with all XBee modules including the Series 1 and Series 2

WAV (PCM and ADPCM)

You can control the output volume using “alsamixer” or any application that supports ALSA mixer controls

1"-spaced pins in case you prefer to use a breadboard

speed-monitoring

This new Adafruit Pi Plate makes it easy to use a blue and white 16x2 Character LCD

Because they have a genuine JST connector

usually the actual current for colorful design is about 1/3 to 1/2 the max current

3V up to 16V and has built-in voltage regulators and signal translators
