3.12 Modifying Hardware Design and Schematic

The following figure illustrates the overview of a schematic for the ATA8352 UWB device. Some components are marked as not mounted (red color cross), as they are not necessary for describing the application use for demo, and TDoA. In comparison to the schematic of Figure 3-6, there are plenty of changes in the BOM. For example, the C6 capacitor quantity changes from 3.3 pF in the ATA8350 UWB device to 1.4 pF in the ATA8352 UWB device. A DC/DC converter is not mounted in the ATA8352 module schematic, as illustrated in the following figure. For more details, refer to the ATA8352 Demo and Evaluation Kit User’s Guide and ATA8350 Demo and Evaluation Kit User’s Guide.
