Where do you think DigiKey is getting thier modules?? They don't make them thierselves.
Yes, but they don't make anything they sell and it's not all priced far higher than other sources.
And the above caution about DPSS modulea blasting out IR is very correct!
Wouldn't you have to shine the laser in your eye for this to be a danger? And wouldn't most people look away if a green laser were shown in their eye regardless of whether there were an infrared component to the beam?
