You can choose maximum 8 different address from 0x20-0x27.The module lead to the Raspberry Pi's GPIO again so you can cascade maximum 8 modules one by one   \u003cbr\u003e    \u003cbr\u003e    \u003cstrong\u003eFeatures:\u003c\/strong\u003e   \u003cbr\u003e    \u003cbr\u003e Input voltage:5V or 3V   \u003cbr\u003e 8 bi-direction IO   \u003cbr\u003e Provide Isolation protection   \u003cbr\u003e Communicate with I2C bus   \u003cbr\u003e Expand 8 modules maximum   \u003cbr\u003e 8 different I2C address that you can choose   \u003cbr\u003e Reverse insert will not disturb the module   \u003cbr\u003e IO definition   \u003cbr\u003e The EXT0-EXT7 are 8 bi-direction GPIO that you can use.
