DescriptionThe LAN Module with W5500 V12 is a wired network base for M5Stack controllers that adds a compact W5500 Ethernet controller and an embedded Ethernet connection for industrial projects. The W5500 Ethernet controller uses SPI communication and supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE, while integrated packet buffers help the base handle Ethernet traffic more smoothly. Reserved expansion pads let the base work with RS485 or RS232 adapter boards, so the embedded Ethernet connection can sit beside field communication interfaces in one installation.For cabinet and production setups, this base includes HT3.96 terminals, a 9 to 24V power input range, rail mounting hardware, and adapter boards for serial communication. This makes the W5500 Ethernet controller useful when an M5Stack core needs a stable embedded Ethernet connection instead of wireless networking.Features LAN Module with W5500 V12 built for wired M5Stack network access.

The embedded Ethernet connection is suitable for projects where the controller must stay on a wired network, and the W5500 Ethernet controller keeps TCP/IP handling inside dedicated hardware. This module can also be paired with the included RS485 and RS232 boards when a project needs Ethernet plus serial links.Because this LAN base ships with DIN rail hardware, magnets, terminals, screws, and headers, it can move from a bench prototype to a small enclosure with fewer extra parts. The embedded Ethernet connection is especially useful for fixed nodes that need repeatable throughput and simpler network troubleshooting.Resources Product documentation Schematic PDF W5500 datasheet FAQWhat does the LAN Module with W5500 V12 add to an M5Stack controller?It adds a W5500 Ethernet controller, RJ45 10/100M wired networking, 9 to 24V power input, and installation accessories for a more stable embedded Ethernet connection.Which protocols are supported by the W5500 Ethernet controller?The W5500 Ethernet controller supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE through a hardware TCP/IP implementation.Can the base work with RS485 or RS232 communication?Yes.
