Overview
AR0004-R1 is an open-source printed circuit board by WizardTim, from the WizardTim/AR0004-R1 repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 100 × 50 mm with 54 parts on 10 nets, routed with 306 tracks and 277 vias.
It is built around the L7805. Its parts include 22 diodes, 10 capacitors, 6 connectors, 5 resistors and 3 ICs. It belongs with the lEDs and displays boards of this library.
Main components
1README
README.mdAR0004-R1
PCB design files for 10W D50/D65 (5000K/6500K ANSI approximate) standard illuminant modular LED panels. Note any 3528 PLCC LED will suffice provided forward voltage and maximum current are accounted for.
Design Notes:
- Potentiometer mounts on LED side of PCB, reverse pins and deadzone resistor in schematic for opposite mounting
- Thermal design of PCB heatsinking for LEDs is insufficient to cool LEDs to a temperature to prolong life, external heatsink & active cooling required for operation at 10W.
- A diffusor is recommended to reduce intensity of reflections and ease eye strain. Folded printer paper can suffice but will reduce efficiency and minorly affect colour point/spectral content.

Questions
How big is the AR0004-R1 PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AR0004-R1 use?
54 parts, built around the L7805. 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 AR0004-R1 KiCad files?
From the WizardTim/AR0004-R1 repository on GitHub, at the commit this page was made from: the board is AR0004-R1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AR0004-R1 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
