Χαρακτηριστικά

On the same I2C port, DFRobot Gravity: I2C Multiplexer solves the address conflict and enables the normal communication with multiple same-address I2C devices.

You just found the sensor you needed, and you want to wire up two or more to the I2C port of your main board, but later you realized that they have the fixed I2C address! That is, you can not directly use them on the same I2C port! Are you out of luck? Now don’t worry! DFRobot Gravity: I2C Multiplexer can easily solve the address conflict on the same I2C port.

This I2C multiplexer is easy to use, plug and plug and no need to weld. 1 multiplexer has 8 I2C ports, this means you can hook up 8 same-address devices at the same I2C port by 1 multiplexer . The default I2C address of the multiplexer is 0x70, and you can adjust from 0x70 to 0x77. In theory, you could hook up 8 multiplexers on address 0x70~0x77 , to control 64 same-address devices. So powerful!
