WARNING: If you buy this it will not be a plug and play experience. Don't use this Laser in a engraver / cutter without casing. This Laser WILL NOT fit on a Elekslaser A3 pro mount out of the box. This Laser is electrically NOT compatible with the MANA (SE) board, if you use the delivered adapter PCP you WILL kill the Arduino on the MANA Board. So, to my experience, delivery was relatively fast direct from China - but with US power supply, I life in Europe so this was inconvenient (I bought a power supply form Leicke 48W 12V 4A 5,5*2,5mm connector - this works very well for schuko) also the Module fits not on my device so I made a baseplate for mounting (I put the plans on github: https://github.com/Fischx/cutter I was able to cut this out of 3mm black acrylic with the original 2 w laser module, needed 14 rounds, though) you should be able to connect the arduino directly to the laser pwm port - but make sure that the mana board is on the same ground ( - on MANA to - on power supply ) than the power supply of the laser at ANY time - I chose to not go this route after my breadboard solution fried the arduino nano and made a litte board with an optocoupler, I will also publish the schematics for that at some point. The laser it self is nice looking and appears solid, it is also pretty heavy so the steppers of the cutter have to work hard, you have to calculate in a litte bit loss in precision. The laser it self is an array of semiconductor lasers with a fixed focus lense and a quite sollid heatsink, the real output power is nowhere near 15 W but it is powerful (probably around 6W but I have no measure device atm) but you have to place whatever you cut on the exact right height - the focal point is quite narrow. Overall it's a mixed bag, there are not many alternatives out there for laser modules with that wavelength and price range - but if you don't know what you are doing and did not have some electronics skills you are in to a bad experience. If you just want to cut thin cardboard you are probably wrong with this thing. The the lack of documentation and a datasheet made me relate to common sense, The pins on the laser are - + pwm -+ is connected to 12 V DC for pwm I use a 5 V signal, it seems to work as well with TTL voltages down to 2 V there is no information available to the range of the pulse width modulation but it works with the standard configuration of the stock laser.
