Use the following guidelines to lay out the CC3220MODAx module with integral antenna, as shown in Figure 10-6.

• The module must have an overhang of 1 mm from the PCB edge.
• The module must have a 6-mm clearance on all layers (no copper) to the left and right of the module placement.
• There must be at least one ground-reference plane under the module on the main PCB.
• For additional Layout recommendations, see the CC3220MODASx SimpleLink™ Wi-Fi^® and IoT Solution With MCU LaunchPad™ Hardware User's Guide.
