Logic Level Converter Bi-Directional Module 8 Channel

The 8-Channel Bi-Directional Logic Level Converter is an essential interface module for connecting devices operating at different voltage levels, specifically designed for seamless communication between 5V and 3.3V logic systems. This versatile converter allows safe interfacing between Arduino (5V), Raspberry Pi (3.3V), ESP8266, ESP32, and various sensors and peripherals without risk of damaging sensitive components.

Featuring MOSFET-based bi-directional level shifting technology, this module automatically detects signal direction and converts voltage levels in both directions without requiring configuration. Each of the 8 independent channels can handle signals up to 400kHz, making it suitable for I2C, SPI, UART, and general GPIO applications. The module includes separate power rails for high voltage (HV) and low voltage (LV) sides, ensuring proper level translation with minimal signal distortion.

The compact PCB design with clearly labeled pins and breadboard-friendly headers makes prototyping and integration straightforward. Built with high-quality components, this level shifter provides reliable performance in mixed-voltage projects including IoT devices, robotics, sensor networks, and embedded systems development. Each channel operates independently, allowing you to convert multiple signals simultaneously while maintaining signal integrity and fast response times.
