8-Channel I2C Multiplexer TCA9548A, 3-5V

Ever wanted to use more than one of the same device on a single I2C bus? Then this TCA9548A multiplexer is exactly what you were looking for.

Connect up to 8 devices with the same I2C address to the multiplexer and use them with a single I2C bus. The TCA9548A chipset is on I2C address 0x70.
Using the pins A0 to A2 you can modify the I2C address to 0x71-0x77 so that you can use up to 8 of these TCA9548A boards on a single I2C bus in theory.
The TCA9548A 8 Channel I2C Multiplexer can be powered with 3-5V which makes it perfect for 5V boards like Arduino as well as 3V computers like Raspberry Pi.
