This means\nthat after 1 expander is transferred, 8 identical addresses can be connected\nto the same I2C port. The device is also in normal use. The default address of\nthis expander is 0x70, the address can be changed, and can be set within 0x70\nto 0x77 according to your needs. In theory, 8 expanders can be cascaded in the\naddress of 0x70 to 0x77, and each expander can connect 8 devices with the same\naddress. This realizes the same I2C port and connects 64 devices with the same\naddress and uses them normally. Very powerful! Depending on the contents of\nthe programmable control registers, any single SCn\/SDn channel or combination\nof channels can be selected. When a timeout or other improper operation\noccurs, the system master can reset the TCA9548A by asserting the \/RESET input\nlow. Parameters: Working voltage: 1.65V-5.5V. IIC clock frequency: 0-400KHz.\nSmall board size: 31.5 mm x 21.4 mm with two M3 mounting holes. Instructions:\nThe \/RESET, SDA, SCL, A0, A1, and A2 pins on the small board are connected to\nthe pull-up 10K resistor, no need to connect externally.
