Arduino Micro with Headers [A000053] - ATmega32U4 Microcontroller, 16MHz, 20 Digital I/O Pins, 7 PWM Outputs, USB HID Support, Compact Design for Embedded Projects, Compatible IDE

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