Questions

How big is the 446RMv1.0 PCB?

It measures 72.4 × 47.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the 446RMv1.0 use?

82 parts, built around the MCP2561-E/SN, PA12, CUHS20S30FS and 2N7002K. 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 446RMv1.0 KiCad files?

From the TMPI5235/446RMv1.0 repository on GitHub, at the commit this page was made from: the board is 446_RM_v1_0.kicad_pcb and its schematic 446_RM_v1_0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the 446RMv1.0 design in my own project?

Its repository states no licence, so its author keeps all rights: ask TMPI5235 before reusing the design.
