M5Stack LAN Module 13.2

The LAN Module 13.2 represents a sophisticated Ethernet controller module that incorporates the W5500 hardware TCP/IP embedded Ethernet controller through an SPI communication interface. This module is designed to support a variety of communication protocols, making it suitable for diverse applications, including industrial automation, the Internet of Things (IoT), data acquisition, and remote monitoring.

LAN Module 13.2 incorporates a built-in hardware TCP/IP embedded Ethernet controller, designated as W5500, which supports a variety of communication protocols, including TCP, UDP, and IPv4, thereby accommodating the diverse requirements of various application scenarios. Furthermore, the module features a dedicated storage buffer area that facilitates the efficient handling of Ethernet data packets. With the inclusion of a signal-isolated gigabit transformer, LAN Module 13.2 effectively converts input signals from the RJ45 interface to the appropriate output signals, achieving electrical isolation and mitigating electromagnetic interference. This design significantly enhances both the stability and reliability of the system.

LAN Module 13.2 is designed to support a DC-JACK interface with input voltages ranging from 9 to 24 volts, along with an integrated DC-DC buck converter circuit. This configuration not only streamlines power management but also ensures a reliable power supply for the entire device. The module features a built-in jumper pin that facilitates chip selection, enabling the simultaneous stacking of two modules to achieve dual Ethernet connectivity. Additionally, it includes a VH3.96 interface, which allows for the seamless integration of supplementary expansion devices, thereby enhancing flexibility to accommodate specific application requirements.

In addition to its functionality as an Ethernet controller, LAN Module 13.2 is applicable in a variety of contexts, including Ethernet-to-Access Point conversion, lightweight web server operations, and the conversion of RS485 to Ethernet data transmission units (DTUs). This module facilitates diverse data transfer and interconnectivity, offering versatile solutions for users.
