I tried to do a Search for Driver Board but it tells me they are common words and not Searchable?
I did order the one suggested from Russia and it does have documentation and a vender that speaks or writes anyway English.
Anyway got this one below, off eBay and surprise it does not work. With 12 vdc applied and zero volts dc in on the TTL input the laser diode is on. Zero signal should equal 0 volts or close to it on the output, and even reversing the signal does not seem to work. As usual the Chinese vender blames the User for not using it correctly. Just a FYI so others do not purchase.
