Inside Sanwu Pocket (pics)

[Nexgen]

Hello members,
Its been a while since i posted something on a forums, but today is the day of my first year on a LPF, but i will make another thread about that.

So today i want to see what is inside of my Sanwu Pocket 638nm(300mw version)

Here's the laser itself:

Laser apart:

Now its time to look into the module:

My eye catched this sanwu driver with marking:

Here's the current consumption at 3.7v and 4.2v:

Then i wrapped everything back.
Yea, its fun to learn something daily

That's kinda neat Nexgen. :thanks: for the breakdown. I've got a couple of Pockets, now I know what and how they come apart. Enjoy, and thanks for the pics!

For some reason your images aren't loading for me.

I can view the page source, grab the image link and open it in a new tab manually, but the images aren't loading in the post. Weird.

What browser are you using?

What browser are you using?

Firefox with uBlock Origin.

Tried it in Edge and they loaded fine, nice teardown!

Just one thing I would like to know is about the driver. Is it buck or linear driver, if somebody know?

Looks like a linear driver to me.

The 405/445/520 versions likely use a boost driver given the higher forward voltages for those diodes. Red LDs have a fairly low forward voltage and will run off of a linear driver and a 3.7V cell without issue.

Very cool Nexgen, thanks for this

The Disconnect extension also blocks userapi.com. What is it and why use it?

Its just a social media image hosting, nothing special here. By the way, what hosting should I use instead of this one?

How much does it cost ?

Nice, I like the threaded design.

I found this DIY host on Sanwu for sale, hopefully they will offer their spiker host at some point.

I see the Guardian host offered there, will ask them if they sell drivers too.
