Bi-Directional 5V to 3.3V 4-Channel Logic Level Converter Module for I2C & Arduino

Product Highlights

Bi-Directional Voltage Conversion - Simultaneously steps 5V signals down to 3.3V and 3.3V signals up to 5V on the same channel, eliminating the need for separate converters.

4 Independent Channels - Four separate data channels allow you to convert up to multiple signals simultaneously.

Wide Voltage Compatibility - Works seamlessly with 1.8V, 2.8V, 3.3V, and 5V devices, compatible with virtually any microcontroller or sensor.

I2C & Arduino Ready - Purpose-built for I2C communication and Arduino projects, with simple plug-and-play connections.

Easy Setup with Included Headers - Straightforward connections to HV, LV, and GND pins get your project running in minutes.

Applications

• Connecting 3.3V sensors to 5V microcontrollers (e.g., Arduino).
• Interfacing I2C devices with different voltage requirements.
• General-purpose logic level shifting in embedded systems.

Description

This bi-directional logic level converter is the perfect solution for interfacing 3.3V devices with 5V systems. It's a compact, 4-channel module that safely steps down 5V signals to 3.3V AND steps 3.3V signals up to 5V simultaneously. No more worrying about damaging your sensitive components!

This versatile level converter is also compatible with 2.8V and 1.8V devices, making it a valuable addition to any electronics enthusiast's toolkit. What truly sets this logic level converter apart is its ability to allow you to set your high and low voltages and reliably step up and down between them on the same channel.

The level converter is very easy to use. The board is powered from the two voltages sources (high voltage and low voltage) that your system is using. Connect the high voltage ( 5 V for example) to the 'HV' pin, low voltage ( 3.3 V for example) to 'LV', and ground from the system to the 'GND' pins.

There are four separate data channels on the converter board, HV1 - LV1, HV2 - LV2, HV3 - LV3, and HV4 - LV4, each capable of shifting data to and from high and low voltages. The number at the end of each label designates the channel of the pin, and the HV or LV prefix determines whether it's on the high voltage or low voltage side of the channel.

A low-voltage signal sent in to LV1, for example, will be shifted up to the higher voltage and sent out HV1. A signal sent in HV3 will be shifted down and sent out of LV3. Use as many of these channels as your project requires. You don't have to use every single one.

These level shifters are purely digital. They can't map an analog voltage from one voltage to another.
