Introduction
Welcome to the new frontier of Arduino-compatible boards, made possible
by the ATmega32U4. No longer does your Arduino need to be harnessed
by an FTDI Cable, or an ATmega8U2, or any chip who’s sole purpose is
acting as an intermediary between your Arduino and your computer.
The SparkFun Pro Micro is a really cool, little development board. It’s an
Arduino-compatible microcontroller, micro-sized, and it accomplishes with
one single chip what old Arduino Unos, Duemilanoves, and Diecimeillas
could never dream of: true USB functionality.
This tutorial also covers the Fio v3, which works a lot like the Pro Micro but
adds features like easy XBee interfacing and LiPo charging.
