Reef Angel Forum

do i have to have the "reef angel" expansion hub or can i buy a hub at my local electronics store?
i have two modules to hook up.. rf and salinity.. i didnt know that i needed an expansion hub.. i am terrible at research..

Yes, it needs to be the Reef Angel Expansion Hub. The standard usb hub won't work.
