Adafruit has this week announced the arrival of the new Arduino compatible TCA9548A I2C Multiplexer to their online shop, which is now available to purchase priced at $6.95.

Some Arduino boards feature the I2C pins in different places, and you can check out the full hardware requirements for all Arduino boards on the Wire Library Reference page.

All that is needed is to connect the I2C pins of the microcontrollers and provide each with power. This project uses an Arduino as the controller and an arbitrary number of smaller ATtiny85 ...

Arduino peripherals, including Arduino shields, sometimes take up multiple I/O pins and leave little room to create a project that requires multiple Arduino peripherals.
