//
//            Recall some Standard Size Screw Holes
//           --------------------------------------
//
//    - M2.5 Screw Dimensions:
//
//        Diameter of Threaded Section:  2.45 mm
//          Diameter of the Screw Head:  4.5  mm
//         Thickness of the Screw Head:  1.5  mm
//
//    - In the DK PCB implement this as:
//
//                 Drill Hole Diameter:   2.7 mm
//                        Pad Diameter:   4.9 mm
//        Solder Mask Opening Diameter:   5.1 mm

//          Diameter of the Screw Head:   5.5 mm
//          M3 Washer Outside Diameter:   7.0 mm
//
//    - In the DK PCB implement this as:
//
//                 Drill Hole Diameter:   3.2 mm
//                        Pad Diameter:   7.4 mm

//               Plane Relief Diameter:   4.5 mm
//          Silkscreen circle Diameter:   7.6 mm
//
//
//
//    - 4-40 Button Head  Screw Dimensions:
//
//        Diameter of Threaded Section:  2.8  mm
//          Diameter of the Screw Head:  5.3  mm
//         Thickness of the Screw Head:  1.5  mm
//
//    - In the DK PCB implement this as:
//
//                 Drill Hole Diameter:   3.0 mm
//                        Pad Diameter:   6.0 mm
//        Solder Mask Opening Diameter:   6.2 mm
//               Plane Relief Diameter:   4.0 mm
//          Silkscreen circle Diameter:   9.0 mm
//



//
//   Add  8  PCB Mounting Holes
//
//     one mounting hole in each corner  set back  6.0 mm from both edges
//     one mounting hole in the middle of each edge  set back  6.0 mm from the edge
//
//   These mounting holes are for  M3  screws  with a washer.
