8 Layout, Bill-of-Materials, and Schematic of the Test PC board

As mentioned previously, the tool creates Gerber files of the sensor, target, and an evaluation PC board layout with a *.pdf file representation of the design. The images below show examples of PC boards created from the tool's default settings.
