Micro is the smallest Arduino/Genuino board to offer the full set of analog and digital pins. The Micro’s processor is as powerful as the Uno’s, but the small form factor allows embedding into tight spaces, invaluable for projects where weight and/or size are important factors. It’s ideal for projects that require a high number of connections with a small footprint. Plus, it fits directly into a breadboard for easy prototyping. The Micro is also capable of emulating a mouse or a keyboard when connected to a computer via USB.
