14.3.2 PCB layout example (QFN)

The PCB layout in this section is a reference layout for the QFN package.

It is highly recommended to use the layout example as presented with the following boundary

clarifications:

• Keep the antenna connection short.

• Connect VBAT supply to component

C6 in the bottom layer.

• Connect IOVDD supply to component

C18 in the bottom layer.
