Boards in 3 GitHub repositories, designed in KiCad, that use the RBR3MM30ATR by ROHM Semiconductor (100uA@30V 30A 30V 3A 510mV@3A Independent SOD-123FL Schottky Diodes ROHS). See how each wires it, with its parts, size, README and files; the RBR3MM30ATR’s symbol, footprint and pinout are on its own page.
