I wasn’t able to add any silkscreen text objects—those operations aren’t supported via the API.
Work done
  • (none)
Tasks that couldn’t be done
  • Create and configure silkscreen text for Audio Out: “GND / 3V3 / D9 BCLK / D8 DIN / D7 LRCLK”
  • Create and configure silkscreen text for OUT1: “GND / VCC / D0 ID / D2 SIG”
  • Create and configure silkscreen text for OUT2: “GND / VCC / D1 ID / D3 SIG”
Remaining tasks
  • Place the Audio Out label adjacent to the AUDIO OUT connector
  • Place the OUT1 label adjacent to its connector
  • Place the OUT2 label adjacent to its connector
  • Set text size and line spacing for legibility and clearance
  • Run a DRC to verify silkscreen clearance
Success criteria
  • None of the labels are present, so no criteria are met.
Recommended next step Please manually add and position the three multi-line text objects on the Top silkscreen layer, adjust their size/spacing, then run a DRC to ensure no clearance violations.

  • Generic Capacitor
    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.
