Hardware

The hardware specification is categorized into five parts. It shows the interfacing and the pinouts of the board and their corresponding functions and diagrams. It also covers the electrical and mechanical parameters of the LX200V30 WisLink 500 Mbps Broadband PLC Module + EVB.

Interfaces

Evaluation Board (EVB)

The EVB provides all the external interfaces required by the PLC module, which include 7V-28 V DCDC, 3.3 V BUCK, DC power Jack, RJ45 Ethernet, and a PLC coupling transformer. The board is suitable for any embedded design that needs a different power circuit. You can easily use the board to evaluate the PLC performance.
