Introduction
Heads up! This is for the PCA9306 breakout v2. If you are using the previous PCA9306, you'll want to
head over to the older tutorial. The package used on the PCA9306 breakout v2 is different from the PCA9306 breakout v1.
The PCA9306 is a dual bi-directional voltage translator for the I2C-bus and SMBus. It works at a range of voltages between 1.2V and 5.0V and doesn't require a direction pin to function. This is a great board for shifting voltages between sensors and your microcontroller.
