Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper 4. Ferrite beads and filter capacitors should be close to VON and VOP pins. The trace from output pins to speaker should be short and wide. The copper width is recommended to be larger than 0.5mm (20m 26
