I have purchased a number of 4mw 650nm laser modules from virtual village but there is no link to a datasheet or any info on what power requirements it has.
4mW 650nm Laser Diode Module This brand new 4mw 650nm red laser module benefits from a super bright light and a substantial 600m range.
Anyone have any ideas as to what kind of voltage they will require. Any links to a datasheet? Any similar products I can compare to?
