I need to read 2 inputs, that have a range of 6 to 9v. I could use voltage divider as a method to reduce the signal strength to below 3.3v. But I would rather use an opto-coupler based method. I found a breakout board that seems like it might work. But I think the breakout is for output not input? Can I flip this board around and use it as input?

The above board uses a TLP281 IC, which appears to be configured on the board for output only? Any one know of a optocoupler board that input oriented?
