Description
I'm using this ancient BLTouch V.1.3 with my Ender 3 Pro and the v4.2.7 mainboard.
As you can see the wiring of this old kit doesn't work with the new 5 pin port on the v4.2.7 mainboard because voltage and ground are switched.
So I kept using the pinboard but there was no option tell marlin that I'm using this pinboard.
Maybe these changes should also be ported to other Creality printers (Ender 3, Ender 3 Pro, Ender 5, CR-10 Mini, CR-10) but I don't feel confident creating an BLTouch config for them.
Benefits
Adding/enabling these options allows me to keep using the pinboard and BLTouch without having to rewire it.
