Is this driver continuous ground?

Adjustable 1-1.5W Blue 445-450nm laser diode driver /1.5A | eBay

I couldn't find any information on it...has anyone used it before?

I know the whole reason for eBay laser stuff is low price, but when it comes to drivers I do NOT trust cheap items. If you want my advice, if you're going to power a 405 or 445 diode, just get a Flexdrive from DTR. No worries about missing documentation or where it's limits actually lie. You know it will work and how to get it to work best, that's why we all use it.

I don't know for a fact - but I would put my money on that actually being a driver intended for case-positive builds. IE, the spring is probably negative, and the driver gets it's positive from the case pin.

I say that for two reasons:
- Other similar drivers have been case positive.
- There appears to be what looks like a "D+" next to what would presumably be the case pin pad.
