All, I have seen references to a change in wiring for the FSLaser Gen4

All,
I have seen references to a change in wiring for the FSLaser Gen4 hobby laser, but when I try to dig deeper, nothing pans out.
My question is: Has anyone installed a smoothie board into a Gen4? I just want to make sure I don’t smoke anything…
TIA

I installed a cohesion3d Mini in mine. Went flawlessly. I just chopped up and repinned the existing connectors to fit.

OK thank you!
