Ebay driver help

[GreenLaser]

hello i was wanting to buy this
2pcs Constant current laser diode driver 80-500mA w/TTL - eBay Stage Lighting, Lighting Effects, Stage Lighting Effects, Electronics. (end time 19-May-10 01:10:30 AEST)

it sais 2pcs so does it contain 2 drivers?
wat does TTL stand for?
if i get it could i attach any LD within the 80-800mw range thus making it universal.
cheers

Those are drivers from o-like - they are good for red diodes, but not for BR ones ..... TTL is the modulation, it mean that the driver have an input that you can use for turn the LD on and off (usually in these drivers, when you put a signal on this input, the Laser diode shut off, and without signal it light on)

kool. do they come with instructions and was it 2 drivers or is 2 pcs for 1 driver
cheers
o yeah and are they hard to use im kinda a beginner
thanks

It looks like you should get two drivers, also keep that ebay page as a "fav" on the off
chance you don't get any instructions with the drivers. The Ebay page right now has all
solder connections for the driver already laid out for easy referrence.

yes i also saw the conections.it might just be the reverse side but those drivers look dif??

 

[HIMNL9]

You can see both the sides on the auction page ..... and yes, the auction is for 2 pieces, as written

 

[GreenLaser]

yea i know its 2 pieces but is it 2 drivers or 2 pieces that are conected together to mke the driver

Hey GL...

if you look at the auction page 1st photo...
you will see 2 identical Printed Circuit Boards attached
together.
Each PCB is a Driver... Therefor 2 PCBs = 2 Drivers...

It would be a good idea to do a little research on the
Forum on building a Laser before spending money on
parts... There are many ways to build a laser and there
are many types of Lasers...
