{"product_id":"soldered-nula-ethernet-w55rp20","title":"Soldered NULA Ethernet W55RP20","description":"\u003cp\u003eAdd wired Ethernet to your project without a separate network chip or a heavy software stack. The \u003cstrong\u003eSoldered NULA Ethernet W55RP20\u003c\/strong\u003e is built around WIZnet's \u003cstrong\u003eW55RP20\u003c\/strong\u003e, a single package that fuses the dual-core RP2040 with the W5500 hardwired TCP\/IP controller and a 10\/100 Ethernet PHY. You get the familiar RP2040 development experience and a full hardware TCP\/IP stack on the same chip, so networking runs in silicon instead of eating your CPU time. Perfect for industrial sensors, building automation, data loggers, and any device that needs a reliable wired connection.\u003c\/p\u003e\n\u003cp\u003eThe board breaks the W55RP20 out along both long edges. The left side carries an 8-pin and a 10-pin header with power rails and most of the chip's GPIO; the right side adds a further 8-pin and 6-pin header. A separate 3-pin header exposes \u003cstrong\u003eSWD\u003c\/strong\u003e for debugging. An \u003cstrong\u003eRJ45 jack with integrated magnetics\u003c\/strong\u003e handles the Ethernet side, with two status LEDs built into the connector. A \u003cstrong\u003eQwiic connector\u003c\/strong\u003e gives you tool-free I2C expansion, a \u003cstrong\u003emicroSD slot\u003c\/strong\u003e (SPI) covers data logging and storage, and an onboard \u003cstrong\u003eTP4056M\u003c\/strong\u003e charger with a \u003cstrong\u003eJST connector\u003c\/strong\u003e lets you run and charge a Li-ion\/Li-po battery. Power and programming come over \u003cstrong\u003eUSB-C\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eIf you know the Raspberry Pi Pico or any RP2040 board, you already know how to program this one. It works with the \u003cstrong\u003eArduino IDE\u003c\/strong\u003e, \u003cstrong\u003eMicroPython\u003c\/strong\u003e, and \u003cstrong\u003eC\/C++\u003c\/strong\u003e, and existing RP2040 code, libraries, and examples run with minimal changes.  A \u003cstrong\u003eUSB-A to USB-C\u003c\/strong\u003e cable is included in the package, so you can start programming right out of the box.\u003c\/p\u003e\n\u003cp\u003eNote:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe W55RP20 does \u003cstrong\u003eNOT\u003c\/strong\u003e support auto-MDIX. Use a straight-through cable to a switch or router, and a crossover cable to another W55RP20, a server, or a workstation.\u003c\/li\u003e\n\u003cli\u003eGPIO logic is \u003cstrong\u003e3.3 V and NOT 5 V tolerant\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eBefore connecting a 3.7 V Li-ion battery, please refer to the detailed technical documentation which you can find in the links below.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Soldered","offers":[{"title":"Default Title","offer_id":65344504136029,"sku":"333407","price":19.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0990\/5029\/1549\/files\/isometric.png?v=1785117289","url":"https:\/\/soldered.com\/products\/soldered-nula-ethernet-w55rp20","provider":"Soldered Electronics","version":"1.0","type":"link"}
