Description: Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux).
The Leonardo is Arduino’s first development board to use one microcontroller with built-in USB. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!
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 a AC-to-DC adapter or battery to get started.

I make most of my projects with this Arduino because of the ability to communicate with a computer like a keyboard or mouse. Makes this Arduino superior to the Uno in my opinion.
I really like this version for the USB connectivity. I’m currently running it as my Cookie Clicker.
Hi, I was able to solder and put together the Leonardo quickly and easily however uploading sketches was more challenging. My windows 7 arduino IDE was very slow and losing the virtual Com port assignment after upload since I was trying to configure a wify shield using the serial monitor to verify the connection, this was frustratingly combursom. I then tried Linux Ubuntu 15.04 the serial FTDI_SIO though present in the kernel would not serially connect with the Leonardo after many hours and forum searches I was able to find a fix that described disabling a process that was taking up resources needed for the serial connection and upload. I am now able to upload sketches through Linux quickly and efficiently. I feel road weary from all the work needed.
Every thing is ok
It’s pretty much what everyone expects out of the beastie. Works precisely as advertised.
Finding the discontinued Arduino Leonardo saved us heaps of time and effort in modifying the Seeduino in order to make a PixyPet robot. My son has been learning a lot of programming as a result of playing with his little robot. Thanks for carrying discontinued Arduinos.
