Here is a rather bad (low resolution, grainy) picture of a circuit board that claims to be a 2-channel 315MHz ASK/OOK type remote controlled relay set. I can identify the relays, but not the big blue boxy thing behind them (see picture, with red-arrow).
Can someone help identify what it is ?
Also, is that white thingy labelled "Carli" part of this blue part, or separate ?
