4 Channels IIC I2C Logic Level Converter Bi-Directional Module 3.3V to 5V Shifter

Overview

When working with a mix of 3.3V and 5V devices, communication can be a challenge. This 4-channel I2C logic level converter bridges the gap safely and reliably. It allows bi-directional signal translation between 3.3V and 5V logic levels, making it an essential tool for any electronics workbench. Whether you're interfacing a 5V Arduino with a 3.3V sensor, or connecting multiple I2C devices with different voltage requirements, this module ensures smooth, glitch-free data transfer.

Key Features

• 4 Bi-Directional Channels: Handles multiple signals simultaneously, perfect for I2C (SDA/SCL) and other digital interfaces.
• Wide Voltage Support: Converts between 3.3V and 5V logic levels, with support for other voltage pairs (e.g., 1.8V to 5V) by adjusting the low-side reference.
• High-Speed Operation: Supports I2C data rates up to 400kHz (Fast Mode) and is suitable for SPI and UART.
• Plug-and-Play: No external components needed; just connect your low and high voltage references and the signal lines.
• Compact Design: Small form factor fits easily into breadboards and projects.
