12 Layout and Bill of Materials (BOM)
The Bill of Materials is shown in Table 1 and includes the manufacturer and part number. The layers of the
printed circuit board (PCB) are shown in top down order. The view is from the top down except for the
bottom silkscreen, which is shown viewed from the bottom. The scale is approximately X1.5. The printed
circuit board consists of 4 layers of 3 ounce copper on FR4 material with a total thickness of 0.050 inches.
