Toni_K PCA9306 Overview
Heads up! This is for the PCA9306 breakout v1. If you are using the v2, you'll want to head over to the other tutorial. The package used on the PCA9306 breakout v2 is different from the PCA9306 breakout v1.
The PCA9306 is a dual bidirectional voltage translator for the I2C-bus and SMBus. It works at a range of voltages between 1.0 and 5.0V and doesn't require a direction pin to function.
PCA9306 Breakout Board
This is a great board for shifting voltages between sensors and your microcontroller.
