Hi,
i was just wondering about the setup of DIY handhelds. With modules in the attached configuration can you, assuming you have an appropriate host, connect this array strait to the battery/s?
sorry for the novice question :),
Matti

Don't connect it straight to a power source or you'll burn the diode. Current needs to be regulated, so it needs a driver. Depending on how many batteries you'll use, you decide if you need a boost or linear driver, perhaps a buck. Check out this thread for more info.

hi, thanks for your reply :) ok so the 'chip' protruding out of the module with the + and - input leads is not the driver?
 
The driver is attached, so yes, it could be attached straight to a power supply and it will work.

edit: yes, that 'chip' is the driver.

i have read the thread on driver types, along with many others on the beginning stages and concepts of DIY, i still have a lot to learn tho :)
if the module is a 3-3.5V input can you have a power supply of either 3 or 3.5V? does the driver make either safe for the diode?

Yes you could. I believe the driver will make sure the appropriate amount of volts are going to it, not too much, not too less (if applicable).

Somebody please correct me if I am wrong.

Those are standard DPSS 532nm Laser Modules.
They require (as you stated for yours) 3.0V to 3.5V
into the Driver (the Green PCB).

Just connect two AA batteries in series to the input
of the Driver PCB. The 2 AA bateries will give you the
3.0C that you need.

Make sure you heatsink that laser before you start using it. Even if it is only a 5mW green, it has a 250mW or larger IR pump diode that needs to be properly cooled.

its the appropiate amperage as well
 
thanks everyone for the advice, it is much appreciated :)
about the heat sink and cooling would the attached host provide adequate cooling? or should i invest in something more substantial? this host also fits a 18650 battery (3.7v), am i able to use this, or would AA's in series be a better option?

That host should be good enough, what is the power of the module?

Yes I believe a 18650 battery is fine.
