Two-Channel Opto-Isolated Relay Board

Add two switching channels to an electronics control project. This relay-module range offers the board on its own or packages with a case or ESP32-C3 component.

✅ Give two switching tasks a place in the build - The two-channel board provides the relay outputs for a correctly designed control arrangement.

Select the Parts for the Complete Circuit

The control interface and relay contacts serve different roles in a project. Match the actual board's supply, trigger levels and contact ratings to the surrounding circuit before making connections rather than transferring another relay module's limits.

Choose the bare board if the project already has its other parts, or check the case and ESP32-C3 package contents where those are needed. An enclosure option does not by itself establish a finished, protected mains-switching appliance.
