Arduino Micro with Headers

Arduino Micro is the smallest board (48mm x 18mm) of the family, easy to integrate it in everyday objects to make them interactive.The Micro is a microcontroller board based on the ATmega32U4 (datasheet), developed in conjunction with Arduino.cc and 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. It also has other implications for the behavior of the board; these are detailed on the getting started page.FeaturesATmega32U4The smallest board of the family20 Digital I/O Pins, 32KB Flash Memory, 16 MHz Clock SpeedBe recognisable as a mouse or keyboardMade in ItalyTechnical detailsDimensions 48mm x18mm x16mmWeight G.W 13gBattery ExcludeMicrocontroller ATmega32U4Operating Voltage 5VInput Voltage (recommended) 7-12VInput Voltage (limit) 6-20VDigital I/O Pins 20PWM Channels 7Analog Input Channels 12DC Current per I/O Pin 20 mADC Current for 3.3V Pin 50 mAFlash Memory 32 KB (ATmega32U4) of which 4 KB used by bootloaderSRAM 2.5 KB (ATmega32U4)EEPROM 1 KB (ATmega32U4)Clock Speed 16 MHzLED_BUILTIN 13Part ListArduino Micro Board with Headers 1Warranty Card 1Sticker Card 1
