Need help to identify chinese relay board
« on: November 24, 2018, 02:45:00 pm »
Hello,
I have bought some componets from chinese sellers and one of them (I don't know which one) has sent me a relay board that I have not ordered. I have no idea what this board does, but it would be interesting to find out. Can anyone recognize this board or read the 4 chinese characters on the inputs to identify what they read? The outputs come from the relay so they are fairly obvious. The board is double-sided, but has no components on the rear side. There is one SOP8 of type STC 15W100 which I believe is a MCU and a LED and a pushbutton. Any help appreciated. Many thanks.
