Can someone help me with this build?

Okay so i'm going to build a 532nm laser for one of my friends and he want a host like this one ---> eBay Australia: Buy new & used fashion, electronics & home d

is it the same as building a normal pen style laser where i just need a module, driver and some batteries? I'm just asking becuase i haven't made one with the keys before.
if i need anything else can you please tell me

yeah bro, the green modules have the diode, lens and driver in 1!
should be ready to rock, just remember the 532nm modules are case positive!
