The ShillehTek I2C Logic Level Converter (3.3V to 5V, bi-directional) lets 3.3V boards safely communicate with 5V devices on IIC/I2C and other digital lines without flaky signals or risking damage. It is perfect when you are mixing systems like Raspberry Pi, ESP32, Pico W (3.3V) with Arduino UNO, 5V sensors, or 5V modules. This bi-directional converter is commonly used on I2C buses (SDA/SCL) and can also be used for other digital signals where clean level shifting matters.

Highly recommend!!

Fantastic board for both beginners and experienced makers! It’s incredibly easy to use!!!!

Works great!

It’s easy to install and is a quality product

Worked

Ease of use

No issues with the unit, specs as described, no setbacks with my project

Great solder

Very pleased with this purchase, great solder and packaging

No complaints!

Works perfectly! Pre-soldered and super easy to use with my Raspberry Pi and Arduino projects — no hassle, just plug and play.

Great product and the quality was good. The price was just right. would purchase from the seller again

Great component

I needed this component for my Pico w to step down the level was shocked how simple it was to use

Great module to have when working with Raspberry Pi and Arduino.

This 4 Channel Logic Level converter works great for converting the 3.3 V signals from a Raspberry Pi to a 5 V signal needed by some sensors and displays. It also works great converting Arduino 5 V signals to 3.3 V signals used by Raspberry Pi and some sensors and displays. It is also useful when you want to use use an Arduino as an I2C device controlled by a Raspberry Pi.Signal voltage is converted in both directions. You just need to supply a Vcc at the voltage on one side and a different Vcc to the other side. This is a useful module.
