Product Overview

The A000057 Arduino Leonardo(plus headers) 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
