For those who are unaware,Arduino Leonardo was already lunched and it brings great features. For me one of the best features is the fact that there is no longer a chip just for the USB connection. The microprocessor Atmel’s ATmegaXU4 already has that funcionality embeded and this allowed a reduction on the cust price. Don’t be surprised if the arduino Uno stops being produced in a near future.
Besides this there are some more new features like:
-4 more digital pins,
-1 more PWM pin and improved timers,
-1 more analogue pin,
-Some changes on the Serial Comm
-Keyboard and Mouse Emulation.
This emulation point is for me a great addition since we can easily use 2 POTS and a button to create a plug and play device to use the mouse pointer on-sceen or another sample would be a datareader that will send the output directly as a keyboard like some barcode scanner do
