Questions

How big is the Power sink only PCB?

It measures 26.2 × 76.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Power sink only use?

179 parts, built around the HUSB238_002DD, BSS138PS, 1N5819WS and SI7223DN. 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 Power sink only KiCad files?

From the fulgidus/hardware repository on GitHub, at the commit this page was made from: the board is cyberdecks/tricorder/power-sink-only.kicad_pcb and its schematic components/led-matrix/addressable-leds-chain.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Power sink only design in my own project?

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