Am I right that my mainboard (see picture) is v1.0 and not v1.1 and so the new laser module E80 is not compatible because my mainboard does not support 24V power supply?
How much is a mainboard v1.1 and what do i have to change that i can use both laser modules A40640 and E80? Only the mainboard?

Yes, upgrade the mainboard to support 24V and support A40640 and E80
