Works as expected and easy to use with an ESP33 microcontroller.

Have ended up purchasing two of these. One for extending switching using one power source and the other for switching 4 different power sources to four different loads.PROSHas individual high/low triggers for each relayHas both NO and NC contacts for each relayCan be configured multiple ways.Can be used to switch either AC or DC loads but must use DC triggersCONSHaven’t found anyOVERALLVery happy I found these. They worked perfectly for my project. Using only for low amperage DC sources/loads so cannot attest to using them at full capacity or on AC loads. Using to switch both 12vdc and 3vdc loads using 12vdc high or low triggers. Note: found some relays that if are 12vdc triggers that they must also have 12vdc loads so look at the specs if needed. This manufacturer has singles/double/ quads even saw an 8 way version. Sure they’d all work the same
