Arduino Leonardo with Headers [A000057]

its perfect its really easy to use it comes on time and even the box its amazing you should buy one or two i really recomend it

Everything Ok

Works perfect

Each Arduino has its own unique set of features while maintaining the compatibility that defines the Arduino standard. Leonardos strong suit, for me, is its ability to communicate with two serial IOs at the same time for a couple of bucks more than the workhorse UNO. This saves a lot of time when talking to the Arduino thru the USB port and the Arduino talking to another serial device (e.g., a XBee radio) at the same time. No more plugging and unplugging USB cables every time you want to change a line of code. WOW!

Well in truth theres only one uart but has a virtual serial port (usb) thats infinitely useful in debugging apps where the uart serial is in use. I will be buying Leonardos from now on or perhaps the mega clones from China which even lower cost.

$35 Leonardo board. Its a great board, no complaints, but if I had to do it over again, Id but the $25 UNO board.

This unit works great. Im using it in some electronic projects Im working on, Im a beginner when it comes to electronics so this arduino along with the uno I have a big help

This board is great given the form factor. I like having the surface mount ATMEL chip given the low profile. In my experience the Arduino is a tough little board. I have never had to replace the ATMEL chip so the socket was not a feature I required. Also given the mini USB connector is a plus. All of the other boards I have use this size of connector.
