Descripción
The Arduino Micro is a microcontroller board based on the ATmega32U4, developed together with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button.
Contains everything needed to support the microcontroller; just plug it into a computer with a micro USB cable to get started. It can be easily placed on a breadboard. The Micro board is similar to the Arduino Leonardo in that the ATmega32U4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Micro to appear to a connected computer as a mouse and keyboard, in addition to a virtual serial (CDC)/COM port.
This board contains all the key features to ensure you can start programming quickly and easily.
