- The Arduino 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.
- It is integrated with 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs).
- Robocraze is the authorized seller of Arduino products in India and you can buy Arduino Leonardo with headers at best prices from Robocraze.
Arduino Leonardo with Headers
The Original 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 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 an AC-to-DC adapter or battery to get started.
The Leonardo differs from all preceding arduino boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary chip (such as an FTDI friend, FTDI cable or the USB/Serial converter on the UNO).
On one hand this means that sketches on the Leo are a little bigger because it’s also handling USB interaction. On the other hand, it allows the Leonardo to appear to a connected computer as a mouse and/or keyboard, in addition to a virtual (CDC) serial / COM port.
This board is only supported in the latest Arduino IDE 1.0.1 so you will also need to update the IDE.

1.What is Arduino Leonardo used for?
- The Arduino Leonardo is a microcontroller board that uses the ATmega32u4 processor. It has 20 digital I/O pins (seven PWM outputs and twelve analogue inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.
2.What is the difference between Arduino Leonardo and Micro?
- Both the Arduino Leonardo and Micro are microcontroller boards that differ in size, pinout, and functionality. The Leonardo uses a single microcontroller to run sketches and communicate with computers via USB, whereas the Micro is a smaller form factor version of the Leonardo that lacks a DC input jack and can also function as a HID or Virtual COM port device.
- The Leonardo has more I/O pins than the Micro, making it ideal for projects requiring more sensors or actuators. Alternative boards, such as the Sparkfun Pro Micro, have a smaller form factor than the Leonardo and may be better suited for projects that require fewer I/O pins.
