Description
Module with a multiplexerem TCA9548A, allows you to connect 8 different digital I2C interfaces to one interface. Works with a supply voltage from 1.65 V to 5.5 V. The address of the output of the I2C bus can be changed, which allows you to connect up to 64 I2C devices. The module is equipped with QWIIC connectors.
| The product is compatible with Arduino
The manufacturer has prepared auser guide that contains the detailed description of the device and an example of connecting to Arduino. |
Connection
The device has a standard QWIIC connector through which you can connect special sensors. In addition, the built-in switches allow you to change the I2C address of the module. This allows you to connect up to 8 modules in one line I2C, and up to 8 devices for each module.
