I've now reverse engineered the JP-1482 board and drawn a schematic of everything.

The micro's connections:

Control signals:

Output to spindle and overcurrent detection:

Power supplies and fan output:

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?

  Are you sure? yes | no

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