    Hi Chris,

    For the CC3220 module, you can design either a 2 or 4-layer PCB. I recommend a 4-layer PCB because you can reference the layout and stackup used in the CC3220MOD LaunchPad design, which we have also certified.

    See the layout guidelines Section 1.8 in the CC3220MOD LaunchPad User's Guide. This section includes general and RF layout recommendations, information on antenna placement/routing, as well as recommended PCB values for both 2 and 4-layer boards.

    BR,
