The W5100 chipset handles all TCP\/IP processing, so the microcontroller only needs to issue a few commands. Data rates of up to 10 Mbit\/s are supported.\u003c\/p\u003e \u003cp\u003eThe SPI interface connects the module to the host system; several digital pins control chip-select and interrupt signals. A 16 kB buffer stores incoming and outgoing data. This memory is the limiting factor in applications involving larger volumes of data or several simultaneous connections. The RJ45 socket accepts a network cable and connects it to the chipset via an integrated transformer.\u003c\/p\u003e \u003cp\u003eThe module requires a stable 5 V power supply and fits directly onto Arduino boards with the standard connector format. The SPI pins must not be assigned twice. An existing local network with a DHCP server simplifies address assignment; static IP configuration is also possible. Larger volumes of data or streaming applications are limited by the buffer size.\u003c\/p\u003e \u003ch3\u003eSafety information\u003c\/h3\u003e \u003cp\u003eThe module is intended exclusively for building prototypes and for testing and development purposes. It is not intended for connection to household electrical circuits or production network segments containing confidential data. Work on or near electrical installations must be carried out by qualified electricians. If you are unsure about integrating the module into existing networks, consult a qualified electrician before commissioning.\u003c\/p\u003e \u003ch4\u003eScope of delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x\u0026nbsp;HanRun HR911105A 15\/10 W5100 Ethernet Shield\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65997845004637,"sku":"F23106788","price":18.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/hanrun-hr911105a-1510-w5100-ethernet-shield-funduino-6851810.png?v=1791493191","url":"https:\/\/funduino.com\/en\/products\/hanrun-hr911105a-15-10-w5100-ethernet-shield","provider":"Funduino","version":"1.0","type":"link"}
