  • PCF8575 Module IO Port Expansion Board

     

    Explain:

     

    Is the I/O pin used up? This powerful module allows users to scale to 16 more I/Os using only two I/Os for control! The PCF8575 is controlled through the I2C interface and has 16 bit quasi bidirectional input/output pins.

     

    On a board 3.3V level converter circuit, if the VCC-VDD pad is not soldered, the level of the PCF8575 is 3.3V. If welded, its level will be the same as VCC

     

    Features:

     

    ● Available library: PCF8575

    ● Working voltage: 2.5-5.5V DC

    ● Working current: 100mA (MAX)

    ● I2C address: 0x20 (default), which can be modified by welding A1 and A2 selection pads.

    ● 16 individually addressable pins.

    ● Each pin can be configured as an input or output

    ● Open drain interrupt output pin for input change interrupt.

    ● Ideal for UNO R3 and other MCU controlled simple relays, buzzers, buttons, and LEDs.
