New Open-Smart PCF8575 IO Expander Board Module I2C to 16IO For Arduino

Have you run out of I/O pins? This great 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 donot solder VCC-VDD pad, the PCF8575 level is 3.3V. If you solder it, the level will be the same with VCC.

Features:

- for Arduino available library: PCF8575

- 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.

- Great for Arduino R3 and other MCU to control simple relay, buzzer, button, led.

Package Includes:

3 X PCF8575 IO Expander Board Module
