Hi folks, looking for a pinout diagram for an Atomstack M150 unit. I bought it as a standalone unit and hooked it up to my Longmill. Everything worked fine until i had to change the motherboard, and realized id lost the wiring diagram.

If it helps, i think the laser was controlled by pins 1, 3 and 5, and the fan was controlled by pins 2 and 4.

Ive looked up a few things online, but the pin order is not quite right.

Thanks!

I couldn’t find a pinout for the M150.  
Probably best to reach out to [support@atomstack.com](mailto:support@atomstack.com) directly.
