I'm really am a rookie when it comes to electronics and I'm trying to learn a few things by myself so I'm basically opening stuff and trying to identify all the components and figure out how it works...
So I have this greenhouse side-curtain roll-up motor control box that has this little black square connector hub / splitter / coupler (I don't know what it is called) that I don't know if has any other function than linking cables one to another. I assume somebody here can identify this for me and tell me if could have a special function? :)
Thanks a lot!
