Questions

How big is the 303ODv2.3 PCB?

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

What parts does the 303ODv2.3 use?

60 parts, built around the 2N7002K and CUHS20S30FS. 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 303ODv2.3 KiCad files?

From the TMPI5235/303ODv2.3 repository on GitHub, at the commit this page was made from: the board is 303_ODv2_3.kicad_pcb and its schematic 303_ODv2_3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the 303ODv2.3 design in my own project?

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