Pro Micro & Fio v3 Hookup Guide
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.
