The shield is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield supports up to four simultaneous socket connections.\u003c\/p\u003e\n\u003cp\u003eThe on-board micro-SD card slot can be used to store files for serving over the network. It is compatible with the \u003ca href=\"https:\/\/www.makerlab-electronics.com\/product\/arduino-uno-r3-italy\/\"\u003eArduino Uno\u003c\/a\u003e and \u003ca href=\"https:\/\/www.makerlab-electronics.com\/product\/arduino-mega-2560-r3-italy\/\"\u003eMega\u003c\/a\u003e. You can access the on-board SD card slot using the SD library which is included in the current Arduino build.\u003c\/p\u003e\n\u003cp\u003eArduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for general i\/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card, but it must be kept as an output or the SPI interface won't work.\u003c\/p\u003e\n\u003cp\u003eNote that because the W5100 and SD card share the SPI bus, only one can be active at a time. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the W5100, set digital pin 10 as a high output.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments\u003cbr\u003e\n\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca title=\"Arduino Ethernet Shield Getting Started Guide\" href=\"http:\/\/arduino.cc\/en\/Guide\/ArduinoEthernetShield\" target=\"_new\" rel=\"noopener noreferrer\"\u003eGetting Started\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca title=\"Arduino Ethernet Shield Page\" href=\"http:\/\/arduino.cc\/en\/Main\/ArduinoEthernetShield\" rel=\"noopener noreferrer\"\u003eEthernet Shield Page\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Arduino","offers":[{"title":"Default Title","offer_id":42292817952959,"sku":"MLE00051","price":800.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/a0773b530a3c2a079ea02a15ebabc5af.jpg?v=1735815360","url":"https:\/\/makerlab.ph\/products\/arduino-ethernet-shield-w5100","provider":"Makerlab PH","version":"1.0","type":"link"}
