A000022 ,Arduino Leonardo ETH Board - ATmega32u4 Microcontroller, Ethernet & Micro SD Connectivity

he Arduino Leonardo with built-in Ethernet and Micro SD card connectivity, enabling direct network communication and data logging without additional shields. Based on the ATmega32u4 microcontroller, the Leonardo ETH allows users to develop network-enabled embedded applications while maintaining the familiar Arduino development environment. The board operates at 5V logic, runs at 16 MHz, and includes 20 digital I/O pins, 12 analog input channels, and multiple communication options such as UART, I2C, and SPI. The integrated WIZnet W5100 Ethernet chip supports TCP and UDP protocols, making this board ideal for IoT, home automation, and web server projects. It also features an onboard Micro SD card slot, enabling local data storage and file handling for more complex applications. The Leonardo ETH includes a Micro USB connector for programming and communication, and PoE (Power over Ethernet) support can be added via an optional module for powering the board through the Ethernet cable.
Key Features:

• ATmega32u4 microcontroller with native USB, allowing direct USB communication and programming.
• Built-in Ethernet (W5100 chip) for TCP/UDP network communication without additional shields.
• Onboard Micro SD card slot for data logging and file storage in network-based applications.
• 20 digital I/O pins (7 PWM channels) and 12 analog inputs for versatile sensor and device interfacing.
• PoE (Power over Ethernet) compatible via additional module for remote powered operations.
• Compatible with Arduino IDE, fully programmable using standard Arduino libraries with networking support.
