Arduino Pro Micro ATmega32U4 5V 16MHz

Description of Arduino Pro Micro Atmega32U4 5V 16MHz The Pro Micro is a microcontroller board based on the ATmega32U4. 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 and a USB mini-b connection. 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 usb-serial converter. This allows the Micro to appear to a connected computer as a mouse, keyboard and game controller, in addition to a virtual COM port.    Please select "Arduino Leonardo" for board & port in Arduino IDE to use it (it has leonardo bootloader inside). Product package doesn't contain any usb cable. Male headers are not soldered.
