Micro R3 ATmega32u4 Microcontroller Board With USB Cable For Arduino

Description:

This Arduino compatible Micro 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:http://arduino.cc/en/Guide/ArduinoLeonardoMicro?from=Guide.ArduinoLeonardo)

This Arduino compatible Micro 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 smaller form factor that enables it to be easily placed on a breadboard.
