K40 to aftermarket controller

Board to convert K40 flatcable to regular XH 2.54 connectors and pin-headers also including relay to switch air-assist (or any other thing that's required)

Currently used to replace the M2 nano board by the Makerbase MKS DLC32 v2.1.

Because it's only outputting 3V a 3V relay board was used and a simple 2N2222 transistor to supply enough current to activate the relay.

GPIO4 (SCL) of the DLC32 is used to enable/disable the relay (but any 3V pin could be connected/used if preferred)
