Overview

The ACEIRMC W5500 SPI to LAN Ethernet Module offers a compact, low-latency way to add reliable Ethernet connectivity to embedded projects. Built around the W5500 controller, it uses a high speed SPI interface up to 80 MHz and includes a hardware TCP/IP stack. This design lets you leverage familiar microcontrollers such as Arduino and STM32 without getting bogged down in complex networking code. This listing includes five modules for bulk prototyping and rapid scaling.

Key capabilities

  • Up to 8 sockets for concurrent services
  • TCP, UDP, ICMP, IPv4, ARP, IGMP, PPPoE support
  • Integrated data link layer and Ethernet physical layer
  • Wake up capability for low power operation
  • Auto negotiation for 10/100 Mbps Ethernet

Power, compatibility, and design

The module operates with 3.3V logic and requires a stable external 3.3V supply capable of at least 200 mA. I/O signals tolerate 5V, making it suitable for mixed voltage boards. The compact PCB measures 23 by 25 mm, ideal for space constrained enclosures and breadboard prototyping. LED indicators show duplex mode, link status, network speed, and activity, aiding quick debugging.

What you get and how to use

  • 5 x ACEIRMC W5500 SPI to LAN Ethernet Modules
  • Compact 23 x 25 mm PCB per module
  • 3.3V external supply required with 200 mA+ current per module
  • 3.3V TTL level interface with 5V signal tolerance

Practical use cases

Ideal for Arduino projects, STM32 prototypes, and WIZ820io RC5 shield integrations where Ethernet connectivity is beneficial. The built in TCP/IP stack can simplify networking tasks, while multiple sockets support basic servers, data streams, or remote control experiments. The small footprint and clear LED feedback help streamline development and debugging in compact systems.

  • Compact footprint fits tight enclosures
  • Multi socket support enables simple servers and data flows
  • Built in TCP/IP stack reduces software complexity
  • Clear visual indicators assist in troubleshooting
