I'm not sure but  assume I received ( as a port of the MINI-CNC ENGRAVING MACHINES T-D ) a clone of the spindle circuit above based on a 8051 microprocessor.  Unfortunately there are NO names added to the two connectors.  I have a picture of the circuit available.  Anybody came across this spindle controller?

Does the PCB look the same? If so I can let you know what pins are what.
