Special Features

  • ★Working Voltage: 2.5 - 5.5V DC; Working current: 100mA(MAX); Application: Great for UNO R3 and other MCU to control simple relay, buzzer, button, led.
  • ★Available Library: PCF8575; I2C address: 0x20(default), can be modified by soldering A1 and A2 selection pads.
  • ★16 individually addressable pins. Each pin configurable for input or output. Open-drain interrupt output pin for input change interrupt.
  • ★PCF8575 module allows the user to expand up to 16 I/O using only two I/O for control! The PCF8575 is controlled through an I2C interface and features 16-bits of quasi-bidirectional input/output pins.
  • ★On board 3.3V level converter circuit, if you do not solder VCC-VDD pad, the PCF8575 level is 3.3V. If you solder it, the level will be the same with VCC.
