  • HDMI, CSI, fan header and Micro SD interfaces extend multimedia, vision and storage options

Dual ETH CM4 Base Board

The LORDWORLD Dual ETH Quad RS485 Base Board (B) is a development board built around a standard CM4 socket. It accepts all Compute Module 4 variants and expands them with dual Gigabit Ethernet ports and four isolated RS485 channels.

Industrial multi-drop RS485 projects

Engineers who need up to 485 multi-drop links over isolated RS485 will find the four channels ready for Modbus or custom protocols. Builds that require wireless connectivity or an M.2 slot for solid-state storage must look elsewhere.

Four isolated RS485 channels

The single specification that decides fit is the presence of four isolated RS485 interfaces on one board. If the application demands that exact channel count, this base board matches it; if fewer or more channels are needed, a different carrier is required.
