Welcome to the range of Arduino Leonardo-compatible boards from PMD Way.
Based on the Atmel/Microchip ATmega32U4 micontroller, the Leonardo gives you a one-chip Arduino and USB solution. Along with all the usual Arduino fun - the Leonardo gives you a solid Arduino-compatible solution with an onboard USB interface.
The one drawback with the Leonardo is that the pinouts are slightly different - even though the shields look exactly the same as used with the Arduino Uno and others. Click here to review the Leonardo pinouts.
