SparkFun Level Translator Breakout - PCA9306

The SparkFun Level Translator Breakout - PCA9306 is an essential tool for every engineer and hobbyist. This dual, bidirectional voltage-level translator breakout is designed to facilitate communication between parts that operate at different voltage levels. With this device, you can easily manage voltage translations, making it easier for different parts to interact seamlessly.

The PCA9306 is a dual bidirectional I²C-bus and SMBus voltage-level translator. It operates on the low side from 1.2V to 3.3V and on the high side from 1.8V to 5.5V. To use it, simply apply your low and high-side reference voltages to the VREF1 and VREF2 respectively, connect your I/O and drive the Enable pin high. This will open bidirectional voltage translation without the need for a direction pin.

SparkFun has improved this classic board by using a new footprint. They have also added a second ground pin and broken out the enable pin. These updates make the PCA9306 more versatile and user-friendly, enhancing its functionality and ease of use.

SparkFun provides comprehensive support for the PCA9306. This includes a detailed schematic, Eagle Files, a Hookup Guide, a datasheet (PCA9306DC), and a GitHub Hardware Repo. These resources are designed to help you get the most out of your PCA9306, whether you're an experienced engineer or a hobbyist.

With the SparkFun Level Translator Breakout - PCA9306, you can easily manage voltage translations, making your engineering projects more efficient and less complicated. This tool is not just functional but also versatile and user-friendly, making it a valuable addition to any engineer's or hobbyist's toolkit.
