Switching Relay for Home Automation System
I am currently planning on using these in a home security project, utilizing the relay to both switch components on/off for my solar panel and PoE cameras.The boards are well made I have not see any issues with mfg. As for any other features I am currently using these as a learning tool for both relay controls and remote control so not much I can comment at the moment on its functionality. But definitely worth the cost for learning.
