All information about the Sculpfun S70 Max diode laser. As soon as I have been able to test it in more detail, I will refine this article further.
Be aware! The S70 also uses the MR30 connectors for connecting the laser heads, but the pins have been changed!! You can’t mount an S30 Ultra or IR-2 laser head to the S70 without further modification!
