PCF8575 I2C port bővítő modul microcontrollerhez (ESP32, Arduino, PIC, STM32 stb... )
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

available library: PCF8575
Working voltage: 2. 5 - 5. 5V DC
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
