See the following checklists through the design process and before the PCB tapeout.

## QRB5165 Schematic Checklist

The schematic checklist is an accumulation of notes from QTI internal reference design and testing. The QTI CE team will use this checklist to verify each customer-submitted schematic design. Consider each of these items when doing your individual product designs. To view the schematic checklist, click [*QRB5165 Schematic Review Checklist* (80-PV086-111)](https://docs.qualcomm.com/bundle/80-PV086-111/resource/80-PV086-111.xlsm).

## QRB5165 Layout Checklist

The layout review checklist is an accumulation of notes from QTI internal reference design and testing. The QTI CE team will use this checklist to validate each customer-submitted layout design. Consider each of these items when doing your individual product designs.
