- markdown tables:
|s should line up - diagram preferences:
- show part numbers; avoid reference codes
- maximize readability:
- shorter wires is better
- avoid using a legend:
- label components directly
- draw all connections
- avoid redundancy (ie. explaining a connection that the diagram clearly displays)

Questions
How big is the 12v PCB?
It measures 50 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 12v use?
51 parts, built around the UCC27524AD, AOD4184A and SMBJ15A. 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 12v KiCad files?
From the MikeBusuttil/kitchenlighting repository on GitHub, at the commit this page was made from: the board is 12v/pcb/pcb.kicad_pcb and its schematic 12v/pcb/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 12v design in my own project?
Its repository states no licence, so its author keeps all rights: ask MikeBusuttil before reusing the design.
