Description

The 4-Channel Bi-Directional Logic Level Converter is a compact and efficient module designed to safely interface devices operating at different logic voltage levels. It enables bi-directional communication between low-voltage logic (such as 1.8V, 3.3V) and higher-voltage logic (such as 5V), making it ideal for microcontrollers, sensors, and communication buses like I²C, SPI, UART, and GPIO.


Key Features

  • 4 Independent Bi-Directional Channels
    Supports simultaneous two-way signal conversion on four lines.

  • Wide Voltage Compatibility
    Works with low-voltage logic from 1.8V–3.3V and high-voltage logic up to 5V.

  • Automatic Direction Sensing
    No direction control pin required.

  • Compact Breadboard-Friendly Design
    Easy to plug into standard breadboards and prototyping boards.

  • MOSFET-Based Level Shifting
    Ensures reliable signal translation with minimal delay.
