Questions

How big is the L6235 double PCB?

It measures 110 × 55 mm and has 2 copper layers, 1.6 mm thick.

What parts does the L6235 double use?

69 parts, built around the MCP2551-I/P. 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 L6235 double KiCad files?

From the ElBabar/L6235_double repository on GitHub, at the commit this page was made from: the board is L6235_double.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the L6235 double design in my own project?

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