Fan circuit board second connector

Hi community,

can anybody tell me what the second JST connector is for on the circuit board on top of the feeder motor?



take a look at this right up, explains other the pins.


These are spare. I’ve used them for my bltouch.

Its a 5v out similar to the other one.

Whats cool about it is you can control it via G-Code (e.g. turning a fan on or off).

Alternatively you can hook up a laser to it or CNC
