PCA9548A I2C IIC Multiplexer Compatible with Arduino

The small I2C multiplexer PCA9548A allows the connection of up to 8 I2C devices. The multiplexer has 8 different I2C addresses, from 0x70 to 0x77. This can also be used to control 8 multiplexers, resulting in 64 different I2C addresses. Using this PCA9548A expansion card is straightforward, and it can be used on a breadboard with capacitors and pullups and pulldowns.  Some headers are required, and once soldered in, you can plug it into a solderless breadboard.  The operating voltage of 1.8V to 5V allows you to run the 8-channel multiplexer at any logic level.

Specifications:
