Arduino Micro - Development Boards & Kits (A000053) (New)

Regular price $31.95

Arduino Micro is the smallest board of the family, easy to integrate it in everyday objects to make them interactive.

The Micro is based on the ATmega32U4 microcontroller featuring a built-in USB which makes the Micro recognizable as a mouse or keyboard.

The Micro is a microcontroller board based on the ATmega32U4, developed in conjunction 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. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to 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 (CDC) serial / COM port.
