The Leonardo ETH is a microcontroller board based on the ATmega32U4 and the new W5500 TCP/IP Embedded Ethernet Controller. 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 RJ45 connection, a micro USB connector, 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 ETH differs from the preceding Ethernet board in that the ATmega32u4 has built-in USB communication, eliminating the need for an external USB-to-serial converter. This allows the Leonardo ETH 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 behaviour of the board. Plus, it has the new W5500 TCP/IP Embedded Ethernet Controller onboard.
An optional Power over Ethernet module can be added to the board as well.
The Leonardo ETH has the same Wiznet Ethernet interface as the Ethernet Shield 2.
