    Red laser Module Question

    I am looking to build a 10mw red laser to be used as a pointer. It seems that AIXIZ has what I am looking for, but I do not see drivers included with the modules. Are they built inside or do I need to get a separate driver. Also, at this low power, do I even need a driver?
