kiss*PCF8575 IO Expander Module I2C To 16IO For Arduino
Descriptions:
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:
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 UNO R3 and other MCU to control simple relay buzzer button led.
