Hello friends, I hope you all are doing great. Today, I am going to share the W5100 Ethernet Module Library for Proteus . The W5100 module is the classic blue Ethernet board for Arduino projects: a WIZnet W5100 - the chip of the original Arduino Ethernet Shield - with a HanRun RJ45 jack, a regulator and a 2x5 header. It takes the TCP / IP work off the microcontroller, and the Ethernet library of the Arduino IDE drives it. With this library you can wire the module to your UNO in Proteus and run those sketches as they are - DHCP, DNS, servers, clients and UDP. Updates W5100 Ethernet Module Library for Proteus Latest version: V1.0 (October 2026, this tutorial) Other Ethernet libraries: Ethernet Shield · Ethernet Shield 2 · W5500 Module · ENC28J60 Module · ENC28J60 Nano Shield · Ethernet Rev3 ...
