3pcs XY-J04 Trigger Cycle Time Delay Switch Circuit Double MOS Tube Control Board Relay Module
A part of the review has been auto-translated.
These timer modules are versatile little units and represent good value for money in the 3 pack. Programming is a little tricky since the instructions on the site are incorrect in places. With a little experimentation it is possible to set them up in several modes. Recommended.

This product gets 4 stars only because it has no outside protection from elements or dirt and dust. Other features are great and setup is easy. Recommended to anyone that makes his own electronics projects
