![]() ![]() If you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. Note that because the W5500 and SD card share the SPI bus, only one at a time can be active. On the Mega, the hardware SS pin, 53, is not used to select either the W5500 or the SD card, but it must be kept as an output or the SPI interface won't work. These pins cannot be used for general I/O. On both boards, pin 10 is used to select the W5500 and pin 4 for the SD card. This is on digital pins 10, 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. Arduino communicates with both the W5500 and SD card using the SPI bus (through the ICSP header). The Shield does not come with a built in PoE module, it is a separate component that must be added on. NB: the Power over Ethernet module is proprietary hardware not made by Arduino, it is a third party accessory. High efficiency DC/DC converter: typ 85% 80% load.The current Shield supports a Power over Ethernet (PoE) module designed to extract power from a conventional twisted pair Category 5 Ethernet cable. Previous revisions of the Shield were not compatible with the Mega and needed to be manually reset after power-up. The Shield also includes a reset controller, to ensure that the W5500 Ethernet module is properly reset on power-up. The original revision of the Shield contained a full-size SD card slot this is not supported. When working with this library, SS is on Pin 4. The onboard micro-SD card reader is accessible through the SD Library. It is compatible with the Arduino Uno and Mega (using the Ethernet library). There is an onboard micro-SD card slot, which can be used to store files for serving over the network. The Ethernet Shield 2 has a standard RJ-45 connection, with an integrated line transformer and Power over Ethernet enabled. The most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO Board. This keeps the pin layout intact and allows another Shield to be stacked on top of it. The Ethernet Shield 2 connects to an Arduino Board using long wire-wrap headers extending through the Shield. Use the Ethernet library to write sketches that connect to the Internet using the Shield. It supports up to eight simultaneous socket connections. The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. It is based on the ( Wiznet W5500 Ethernet chip). The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the internet. ![]() Contact us through our Customer Support.Get assistance with your projects in the Arduino Forum.Learn more on the Ethernet Shield 2 in the Ethernet2 Library reference.In the Getting Started section, you can find all the information you need to configure your board, use the Arduino Software (IDE), and start to tinker with coding and electronics. You can find your board warranty information here. Ethernet Controller: W5500 with internal 32K buffer.Operating voltage 5V (supplied from the Arduino Board).*Requires an Arduino Board (not included) Hundreds of thousands of Arduino Boards are already fueling people’s creativity all over the world, everyday. This means you can learn exactly how it's made and use its design as the starting point for your own circuits. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. Just plug this module onto your Arduino Board, connect it to your network with an RJ45 cable (not included) and follow a few simple steps to start controlling your world through the internet. This allows the Leonardo to appear to a connected computer as a mouse and keyboard.The Arduino Ethernet Shield 2 connects your Arduino to the internet in mere minutes. The Leonardo differs from other Arduino boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. The keyestudio Leonardo can be powered via the micro USB connection, or via an external power supply jack (DC 7-12V) or even with female headers Vin /GND (DC 7-12V). Note that ICSP (In-Circuit Serial Programming) header can not only program the firmware to Atmega32u4, but also be used as SPI communication interface. 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. It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. ![]() It is an easy-to-use open source hardware.
