Kobee Studio's tools solve different board-communication problems. Start with the simplest tool that makes the board clearer, then keep the result editable.
Labels and symbols
Use labels for names, instructions, warnings, interface markings and revision text. Add a symbol when a familiar visual communicates faster than words. Filled, inverted and outline treatments, rounded shapes, padding, borders and optional underlines keep the result consistent.
Header overlays
The 2.54 mm single-row header tool creates a readable pin rail over a connector. Choose horizontal or vertical orientation, the pin-1 end, label side, spacing and optional openings. The overlay describes the connector without changing its electrical footprint.
Component callouts and arrays
Use a component callout when a label needs to sit around a real package, LED, switch or custom envelope. Use a component array for repeated parts such as LED banks. Keep enough clearance that the part remains visible and serviceable.
QR codes and barcodes
QR and Code 128 tools create machine-readable markings with guarded minimum sizes and quiet zones. You can add a separate human-readable line below the code; changing that line does not change the encoded payload.
Output layers
Front and bottom silkscreen are usually the clearest home for board labels. Copper and solder-mask artwork can be useful for specialist designs, but they need a tighter manufacturing review. Avoid using courtyard layers for decorative artwork.
