I2C Logic Level Shifter Module – 3.3V to 5V Bidirectional Converter

Description

The I2C Logic Level Shifter Module (3.3V to 5V) is designed to safely interface 3.3V and 5V logic devices in I2C and other low-speed digital communication systems. It enables bidirectional voltage translation, protecting sensitive microcontrollers from over-voltage damage.

This module is commonly used when connecting 3.3V boards such as ESP8266, ESP32, and Raspberry Pi with 5V devices like Arduino, displays, and sensors. Built using MOSFET-based level shifting, it supports reliable two-way communication without signal distortion.

Compact, breadboard-friendly, and easy to use, this level shifter is an essential component for IoT, embedded systems, and prototyping projects.
