Wiznet W5500 Ethernet network module RJ-45 WoL SPI TCP/IP UDP 2.54 mm STM32

W5500 Ethernet RJ-45 SPI TCP/IP module for Arduino, ESP32, ESP8266, Raspberry Pi The Ethernet W5500 RJ-45 network module is a compact expansion for microcontrollers such as Arduino, STM32, ESP32, ESP8266, and Raspberry Pi. The faster, more capable Wiznet W5500 chip is a direct successor to the popular W5100. The module includes a built-in hardware TCP/IP and UDP stack. It is ideal for projects where Wi-Fi is insufficient or simply unstable. The chip is fully compatible with the Wiznet Arduino IDE library. Key technical specifications
