The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature ...

Finally, [James] designed and 3D printed a neat enclosure for the Arduino-USB interface, which makes it look almost as sleek as the original CommsLink module. Perhaps with a bit of further ...

It's like a shrunken version of the Arduino Leonardo as it features the same ATmega32U4 microcontroller, micro-USB port, and pinouts. It also operates at 5V and requires an external supply of 7 to ...

Conversely, the Uno's pins are female. Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you ...
