Description
- Arduino Leonardo R3
Arduino Leonardo; It is an Atmega32u4 based microcontroller board. It has 20 digital input/output pins (7 of them can be used as PWM outputs, 12 of them can be used as analog inputs), 16Mhz crystal, micro USB socket, power socket, ICSP connector and reset button.
There is everything necessary for the operation of the microcontroller on the board.
It can be easily connected to a computer via a USB cable, powered by an adapter or a battery.
The biggest feature that distinguishes Leonardo from many other Arduino models is;
It is the internal USB communication feature on the Atmega32u4.
This way there is no need for a second usb-serial converter processor like the 16u2.
In this way, apart from the virtual COM port ( CDC), Leonardo can be used by connecting to the computer as a mouse or keyboard.
