Base LAN

Description

Although M5 core is ESP32-based, having Wi-Fi and Bluetooth intergrated, it doesn't stop you enable the

Ethernet function. This LAN is a M5 Base that having a W5500 chip, which is a Hardwired TCP/IP

embedded Ethernet controller that provides easier Internet connection to embedded systems. This Base is

speciffically design for industrial application scenarioes, comes with couple of HT3.96 connectors, 485(?)

metal rail and magnet discs for easy installation and fixation.

The 6 pin of HT3.96 connector are dangling, you can wired them up with the M-BUS and other circuit as

you like.

The figure below shows the inner of LAN

If you need to add RS485 interface, soldering the RS485 board onto the mian board pin correspondingly.
