ARDUINO MICRO WITHOUT HEADERS Code A000093 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 USB which makes the Micro recognisable as a mouse or keyboard. The Micro is a microcontroller board based on the ATmega32U4 datasheet , 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.

Arduino / Genuino Micro is open-source hardware! You can build your own board using the follwing files:

Programming

The Micro board can be programmed with the Arduino Software IDE . Select "Arduino/Genuino Micro from the Tools > Board menu. For details, see the reference and tutorials.

The ATmega32U4 on the Micro comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the AVR109 protocol.

You can also bypass the bootloader and program the microcontroller through the ICSP InCircuit Serial Programming header using Arduino ISP or similar see these instructions for details.

Warnings

The Micro has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.

Power

The Micro can be powered via the micro USB connection or with an external power supply. The power source is selected automatically.
