Trying to identify these tiny drivers.

Hey all, been a while since I posted. The last few years have been a roller coaster to say the least. My interests have shifted focus (pun intended) from lasers to CNC, Microscopy, drones, fractal artwork, robotics, and parenthood. Yet once again, here I am, grateful for this wonderful esoteric community of fellow obsessed laserists. It's good to be back

Anyway, here recently I've been working on cleaning out and organizing my hoard of laser related bits and pieces. I came across these little tiny drivers that I vaguely remember ordering on amazon, way back when I first started to experiment with building my own modules.
Assuming the anti-static bag they were in is actually from them, they were sold by Lilly Electronics/Q-baihe. The little bag has the number L4-4-1, along with a UPC code of 6 240379 0134850.
I can't find anything online for these. Hoping someone can assist in finding documentation of a pinout for the pads (pad-out?) and/or specs for voltage/current/wavelength.
TBH, they're probably not anything special, but they are unusually tiny drivers that I'd like to put to some use if possible. The last pic shows just how tiny they are next to a 5.6mm diode, sitting on a coin.

I have a red one I pulled from some broken gadget that looks like that with the exception of the trim pot. It was mated to a low power 5-20 mw red either 650 or 638nm.

Right on, thanks for the details.
