schematic for BOB1205 breackout board

Just in case anyone needs it I sat for a couple of hours with a multimeter and a BOB1205 and created a schematic from what I found. It's really pretty straight forward with no surprises. I'm posting just in case it might save somebody some time and trouble. You can get a data sheet for the EL817C by just googling for: opto coupler EL817 data sheet

Thanks for taking the time to post it.

Hopefully it will save someone a lot of effort in the future.

regards
