The PCB layout in the following figure is a reference layout for Circuit configuration no. 1 for QKAA aQFN™94.
Note: Pay attention to how the capacitor C1 is grounded. It is not directly connected to the
ground plane, but grounded via pin J31 and to the VSS die pad. This is done to create additional
filtering of harmonic components.
For all available reference layouts, see the product page for nRF5340 on www.nordicsemi.com.
