        1PCS Leonardo R3 Atmega32u4 controller compatiable Arduino Leonardo R3 NEW                 Description:                The Leonardo 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, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.       The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.       Specifications:               Microcontroller: ATmega32u4         Operating Voltage: 5V         Input Voltage (recommended): 7-12V         Input Voltage (limits): 6-20V         Digital I/O Pins: 20         PWM Channels: 7         Analog Input Channels: 12         DC Current per I/O Pin: 40 mA         DC Current for 3.3V Pin: 50 mA         Flash Memory: 32 KB (ATmega32u4) of which 4 KB used by bootloader         SRAM: 2.5 KB (ATmega32u4)         EEPROM: 1 KB (ATmega32u4)         Clock Speed: 16 MHz             Package include:               1x Leonardo         1x USB Cable
