About filter capacitance material and placement quantity
Capacity material recommended to use X7R material, placing quantity suggest that the corresponding
chip should have at least one 104pF capacitors at the each supply pin, and some special entrances
suggest placing the 104 pF+10 uF combination.
Detail please refer to NuMaker-emWin-RDK-N9H20 schematic diagram for details.
The layout pattern and the filter capacitance placement are shown in the image below.
