IC I2C interface Level Conversion Module 5V <-> 3V System
The I2C Logic Level Conversion Module 5V ↔ 3.3V is a compact interface board designed to enable reliable communication between 5V and 3.3V I2C devices. It safely converts logic levels between different voltage systems, making it ideal for connecting 3.3V sensors, modules, and microcontrollers to 5V development boards. The module includes a built-in 3.3V voltage regulator capable of supplying up to 100mA, eliminating the need for an external regulator in many applications. Compatible with breadboards and prototype circuits, it provides a simple and effective solution for voltage level matching in embedded systems and electronics projects.

The I2C Logic Level Converter Module is designed to bridge communication between devices operating at different logic voltage levels, specifically 5V and 3.3V systems. It allows safe data exchange over the I2C bus by converting the SDA and SCL signal levels between high-voltage and low-voltage devices.
The module features dedicated connections for both voltage domains, making integration straightforward. A built-in 3.3V voltage regulator converts a 5V input into a regulated 3.3V output with up to 100mA current capability, which can be used to power compatible low-voltage modules.
Its breadboard-friendly design makes it suitable for rapid prototyping, educational projects, sensor interfacing, and embedded system development. The converter helps prevent damage caused by voltage mismatches while ensuring reliable communication between devices operating at different logic levels.
