Addressable RGB LED, side view

Side-emitting addressable RGB LED with the WS2812-type single-wire protocol, for status lights that shine out of the edge of a board. Local decoupling on the supply; data in and data out are brought out, so several blocks chain into a string. The labels carry the block ID, so several instances can sit on one sheet.

Key specifications

  • Supply 3.7–5.5 V
  • Single-wire 800 kHz protocol (WS2812-type)
  • Data out regenerated for the next LED

Design notes

  • At 5 V the data input needs 5 V logic: from a 3.3 V MCU put the 0040 level translator in front.
  • Not built yet: one LED pin assignment is still to be confirmed against the datasheet before the first build.
Coming soon

This block is not available yet. It is released once its checks are complete. Planned price: €29.

FAQ

Which KiCad version do I need?

KiCad 10. The files are saved in the KiCad 10 format and are meant to be placed with KiCad’s Design Blocks feature (schematic block, then “Apply Design Block Layout” on the PCB).

Do I need the Circuit Issues part library?

No. Symbols are embedded in the schematic and footprints in the PCB, so the block opens on its own. Parts carry manufacturer part numbers and LCSC codes.

Is the layout production-ready?

The layout fragment passes the KiCad design rule check. Route it into your board and run DRC with your own fab rules.

Can I use the template in a commercial product?

The licence terms are published together with the first release.
