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
