laser module TTL vs PWM #13

Ok, Houston, we have a problem.

I order a second minilaser diode for fabmob but I was not please with the first one and I order the same used by bemaker this time. The machine is arrived, it's mounted but the laser module is lost somewhere. Hopefully, I bought earlier another laser module as safety parts. and because it's never easy and never work on the first attempt, connectors don't fit.

It's same same as the first (I was thinking) image

But with Eleksmaker, it's a 3pin cable for the same module but like this. image

The control board is the "SW-LD62 v2" And I found this part. image

Description: This PWM TO TTL laser module is design for EleksMaker series machine and its controller board. But it can also be used for other DIY machine which need to change TTL modulation.

Specification: Power port size: 5.5*2.1mm Working voltage: DC 12V Woring power: >2A

Eleksmaker use the mana board controler. image

The other is laseraxes board. image Seems less good than the other. And the power supply connector is a bit loose, it doesn't match the size of the power supply (2.5mm vs 2.1mm probably, tssss) But have 2 place to connect laser, depending of the laser power. both 2pins. note: I have a second mana board... ^^

So my question is simply, "what about unsolder 2pin connector and solder 3pin connect instead?" Right?
