Boards in 2 GitHub repositories, designed in KiCad, that use the LM358ADR by UMW (-16V~16V 0V~36V 0℃~+70℃ 1.1MHz 1mA 2 20mA 3nA 45nA 55nV/√Hz@1kHz 5mV 600V/ms 7uV/℃ 85dB SOP-8 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the LM358ADR’s symbol, footprint and pinout are on its own page.
