PCF8575 - 16 BIT I2C SMBus General Purpose I/O Expander Module

The PCF8575 I/O Expander Module is based on PCF8575 Chip. The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I2C interface [serial clock (SCL), serial data (SDA)].

    The device features a 16-bit quasi-bidirectionalinput/output (I/O) port (P07–P00, P17–P10), including latched outputs with high-current drive capability for directly driving LEDs. Onboard 3.3V level converter circuit, if you don’t have a solder pad of VCC-VDD, the PCF8575 level is 3.3V. If you solder it, the level will be the same as with VCC.



    Features

        • Working voltage: 2.5 - 5.5VDC
        • Working current: 100mA(MAX)
        • 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.
        • Ideal for R3 and other MCUs to simple relay, buzzer, button, led.
