Questions

How big is the BLLED PCB?

It measures 28 × 51.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BLLED use?

11 parts, built around the IRLB8721PBF. 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 BLLED KiCad files?

From the Luro02/pcb-blled repository on GitHub, at the commit this page was made from: the board is BLLED.kicad_pcb and its schematic BLLED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BLLED design in my own project?

Its repository states no licence, so its author keeps all rights: ask Luro02 before reusing the design.
