ARDLE-000057


The 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.

More info

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.

Features:

  • ATmega32u4 microcontroller
  • 5V operating voltage
  • 7-12V input voltage
  • 6-20V input voltage limits
  • 20 digital I/O pins
  • 7 PWM channels
  • 12 analog input
  • 40mA DC current per I/O pin
  • 50mA DC current for 3.3V pin
  • 32KB flash memory
  • 2.5KB SRAM
  • 1KB EEPROM
  • 16MHz clock speed
