The default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77.
In the address of 0x70~0x77, 8 expanders can be cascaded, and each expander can be connected to 8 devices with the same address, so that the same I2C port can be connected to 64 devices with the same address and can be used normally.
The chip is compatible with 3V and 5V and can be used with any logic level
