Arduino Leonardo

Produktbeschreibung

Das Arduino Leonardo ist ein günstiges Arduino Board welches auf dem ATmega32U4 aufbaut.

The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). 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.

The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. It also has other implications for the behavior of the board; these are detailed on the getting started page.

This version of the Leonardo comes without headers.

FAQ:

Q: Is the board compatible with all Arduino shields?

A: In general yes. But note that the SPI pins are not led out to the standard pins and the ext. IRQ pins are also not equal.
