Questions

How big is the Lh60 PCB?

It measures 285.8 × 95.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Lh60 use?

152 parts, built around the RP2040-TINY and 1N4148WS. 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 Lh60 KiCad files?

From the TWT233/lh60 repository on GitHub, at the commit this page was made from: the board is lh60.kicad_pcb and its schematic lh60.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lh60 design in my own project?

Its repository states no licence, so its author keeps all rights: ask TWT233 before reusing the design.
