LAN Module with W5500
SKU: K012-B
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.

Datasheet - W5500
The 6 pin of HT3.96 connector are dangling, you can wired them up with the M-BUS and other circult
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.
TTL-to-RS485 adapter board and LAN base
The figure below tells you how the TTL-to-RS485 adapter board connected onto LAN backplane
The serial port pins on the RS485 board will be connected to the GPIO16 and GPIO17 of the LAN backplane.
