Arduino (A000052) Development Board, Arduino Leonardo

Product Information: Silicon Manufacturer: Atmel No. of Bits: 8bit Silicon Family Name: ATmega Core Architecture: AVR Core Sub-Architecture: megaAVR Silicon Core Number: ATmega32 Kit Contents: Evaluation Board for ATMEGA32U4 MCU Product Range: - Product Overview The A000052 Arduino 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 16MHz 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 board 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. It also has other implications for the behaviour of the board. ATmega32u4 8bit AVR RISC based microcontroller Arduino Leonardo can be powered via the micro USB connection or with an external power supply The board can operate on an external supply of 6V to 20V Built in LED connected to digital pin 13. When the pin is high value, the LED is on The board appears as a generic keyboard and mouse, and can be prog to control these input devices USB Over current Protection The maximum length and width of the Leonardo PCB are 2.7inches and 2.1inches
