20 parts5CC0-1.0
Boards using the LM358P
20 boardsBoards in 19 GitHub repositories, designed in KiCad, that use the LM358P by Slkor (-1.5V~18V 0℃~+70℃ 1MHz 2 2mV 3V~36V 3nA 40mA 45nA 500uA 85dB Built-in compensation DIP-8 Operational Amplifier ROHS). See how each wires it, with its parts, size, README and files; the LM358P’s symbol, footprint and pinout are on its own page.
