Much more compact that 8 individual Iso-optocouplers
Device is as expected. A must for my Beagle Bone system. I fried my first BBONE because I failed to Isolate the IO.

Nice optocoupler
This board seems well made and if of acceptable quality. It works exactly as intended with up to 24V input/output. Well done!

Good board but know it's limits.
Device is well made and works as advertised. There are some things to consider however. 1.) the output end of the board is NPN only and it's for small current loads. 200mw rated. It can latch a relay coil probably but it's not a motor driver. For that you need a board with power fets. 2.) although the input is capable of NPN or PNP activation it's only one or the other for all 8 channels. You cannot use NPN trigger on one channel and PNP. on another. For me this is somewhat a issue. But for others it might not be.
