Boards using the PCA9557D
6 boardsBoards in 5 GitHub repositories, designed in KiCad, that use the PCA9557D by Texas Instruments (-40℃~+85℃ 10mA 1uA 2.3V~5.5V 25mA 4.1V 400kHz 700mV 8 8 I2C、SMBus No Interrupt Output Push-Pull、Open-drain Reset function、Cascade and address expansion、Built-in LED driver SOIC-16 I/O Expanders ROHS). See how each wires it, with its parts, size, README and files; the PCA9557D’s symbol, footprint and pinout are on its own page.
