I found this Taobao around the end of 2019.
It really intrigued me due to its small size and specifications. And better yet, it costs lest than 1 USD per driver :D
According to the spec sheet, it takes anywhere from 2-7V input, and outputs 6.8V. It is designed to deliver 280mA.

So i ordered a few.

This is how it is mounted. You thread the diode pins through the holes in the driver and just put a small blob of solder on it to secure the driver in place.
As you can see, it is super tiny. Making it ideal for compact builds.

Here are some before and after pictures for comparisons.

Here you can see my super dim and underpowered 515nm sharp, compared to my 107mW 505nm sharp.
I decided that it was time to make it brighter. So i swapped out the old driver for this new tiny guy.
