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. ⚙️ Key Features Converts logic levels 3.3V ↔ 5V Bidirectional voltage translation Ideal for I2C communication (SDA & SCL) MOSFET-based design for safe level shifting Compact and breadboard-friendly module Simple wiring and reliable operation Protects low-voltage microcontrollers �� Technical Specifications Low Voltage Side (LV): 3.3V High Voltage Side (HV): 5V Channels: 4 (SDA, SCL general I/O) Communication: I2C / Digital signals Operating Type: Bidirectional Module Type: Logic Level Converter Mounting: Breadboard compatible �� Applications Arduino ↔ ESP8266 / ESP32 interfacing Raspberry Pi sensor connections I2C device communication OLED / LCD display interfacing IoT and embedded system projects Educational and lab experiments �� Package Includes 1 × I2C Logic Level Shifter Module (3.3V–5V) �� Delivery Information ✔ Home delivery available in Vijayawada✔ Secure packaging✔ Bulk orders supported
