USR-ES1 W5500 Ethernet Module – Hardware SPI to LAN TCP/IP for 51/STM32 MCU (W5100 Upgrade)
USR-ES1 W5500 Ethernet Module – Hardware SPI to LAN TCP/IP for 51/STM32 MCU (W5100 Upgrade)
The 0USR-ES1 W5500 Ethernet Network Module is a compact, high-efficiency hardware TCP/IP module designed to provide reliable Ethernet connectivity for microcontroller-based systems such as STM32, Arduino, and 8051 (51 series). Powered by the W5500 chip, it offers significant performance and stability improvements over the older W5100, including reduced power consumption, higher transmission efficiency, and enhanced protocol support.
This module uses SPI (Serial Peripheral Interface) for communication, allowing seamless integration with a wide range of development boards and embedded systems. It supports essential internet protocols such as TCP, UDP, ICMP, IPv4, ARP, IGMP, and PPPoE, enabling robust and secure wired networking for IoT, industrial control, and embedded network applications.
The onboard RJ45 LAN port ensures stable and fast physical connections, while the module's compact footprint makes it ideal for space-constrained projects.
