README
README.mdPulse-LED: Copper core board for housing LEDs
This board is designed to interface with Pulse. It houses 8 LEDs in series and features footprints for 2512 high power resistors.
Overview:
Solid copper PCB seats 8 ams-OSRAM 3030 LEDs. This has been used with the green OSLON SSL 80: GT CS8PM1.13-LSLU-26-1. The silkscreen is marked with a dot for the cathode. LED footprints can be jumped to allow the use of fewer than 8 LEDs, however, the central thermal pad of the footprint would need to be covered before jumping. Kapton tape was used to achieve this:
Features:
- Thermal pad on LED connects directly to copper core.
- Resistor pads for jumping, or fixed resistance.
Development:
Summer 2025:
- Board design with LED research and choice.
- Initial full 8 LED board populated and tested with low current (~20ma).
- Use of CA11663_HEIDI-RS TIR lens for focussing LED.
Summer 2026:

Questions
How big is the LED PCB?
It measures 66 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED use?
16 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LED KiCad files?
From the william-richards1/Pulse-LED repository on GitHub, at the commit this page was made from: the board is LED heatsink board/LED/LED.kicad_pcb and its schematic LED heatsink board/LED/LED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED design in my own project?
Its repository states no licence, so its author keeps all rights: ask william-richards1 before reusing the design.
