Product detailed description

RobotDyn Leonardo Ethernet V2 W5500 Micro SD, Compatible with Leonardo ETH, Version with PoE

The Leonardo + Ethernet (Leonardo ETH) is a microcontroller board based on the ATmega32U4 and the newly integrated W5500 TCP/IP Ethernet controller with PoE.

It has 22 digital input/output pins (7 of which can be used as PWM output and 12 as analog inputs), a 16 MHz crystal, RJ45 connection, micro USB connector, power connector, ICSP and Reset button.

It contains everything needed to support the microcontroller. Just connect it to your computer with a USB cable or power it with an AC-DC adapter or PoE to get started. With a safer and more professional power control chip, the system can operate in much more complex environments. And forget about power problems, because it works with PoE power.

Arduino Leonardo is an electronic board equipped with an ATmega32U4 microcontroller. The board provides amazing measurement, monitoring and device control capabilities using a simple C++ based programming environment. The software package includes a lot of examples and libraries for controlling other extension modules (shields).

Leonardo differs from all previous Arduino boards in that the ATmega32U4 microcontroller has a built-in USB interface, so there is no need to use additional special circuits to communicate with the computer. Leonardo can appear to the connected computer as either a mouse and keyboard or as a virtual (CDC) serial/COM port.

Remark:

• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
• W5500 and SD communicate with ATmega32U4 via SPI bus. Pin 10 and pin 4 are the chip selections for the W5500 and SD. They cannot be used as general I/O.
