There are 8 I2C interfaces on one expander, and there are eight bidirectional transfer switches that can be controlled by I2C bus. This means that after 1 expander is transferred, 8 identical addresses can be connected to the same I2C port. The device is also in normal use. The default address of this expander is 0x70, the address can be changed, and can be set within 0x70 to 0x77 according to your needs. In theory, 8 expanders can be cascaded in the address of 0x70 to 0x77, and each expander can connect 8 devices with the same address. This realizes the same I2C port and connects 64 devices with the same address and uses them normally. Very powerful!
Depending on the contents of the programmable control registers, any single SCn/SDn channel or combination of channels can be selected. When a timeout or other improper operation occurs, the system master can reset the TCA9548A by asserting the /RESET input low. Parameters:
Working voltage: 1.65V-5.5V
IIC clock frequency: 0-400KHz
Small board size: 31.5mm x 21.4mm with two M3 mounting holes
Instructions:
The /RESET, SDA, SCL, A0, A1, and A2 pins on the small board are connected to the pull-up 10K resistor, no need to connect externally. Package included:
5 * TCA9548 TCA9548A I2C IIC Multiplexer Breakout Boards

Platinen ähneln maximal den Produktbildern. Die Bezeichnung TCA fehlt bei meinen gänzlich.Außerdem sind 2 von 5 bereits Defekt angekommen.
