Custom Donut PCB Design

Now place all components on the PCB. The board shape is a donut/annular ring, outer diameter 160mm, inner diameter 110mm. Place all LED components in two circular arrays on the top side: 50 WS2812B at 150mm diameter and 30 WS2812B at 130mm diameter. Place all other components on the bottom side compactly between 6 o'clock and 10 o'clock position.

Done.
  • Placed the LED and decoupling arrays in two circles:
    • 50 devices at 150 mm diameter
    • 30 devices at 130 mm diameter
  • Placed the remaining electronics as a compact cluster in the 6 to 10 o'clock region.
  • Set the board to a 160 mm circular 2-layer layout for placement.
Note:
  • The current layout shape workflow only accepted a single continuous outline, so I could not encode the 110 mm inner donut cutout directly in this placement step.
  • The component placement follows your intended annular geometry, but the actual inner cutout still needs to be applied separately.

  • Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
