This great module allows the user\nto expand up to 16 I\/O with only two I\/O to control! The PCF8575 is controlled\nvia an I2C interface and features 16-bit quasi-bi-directional input\/output\npins. If you do not solder the VCC VDD pad, the PCF8575 level is 3.3V. When\nyou solder it, the level at VCC is the same. Features: Main chip: PCF8575\nWorking voltage: 2.5 - 5.5 V DC. Working current: 100 mA (max).
