About this item

🔌 Bi-Directional Logic Level Converter - 4 Channel

💡 Safe & Versatile Voltage Translation

The 4-Channel Logic Level Converter makes it easy to shift signals up or down between systems operating at 1.8V, 3.3V, and 5V logic levels. Its compact design is ideal for breadboards and embedded projects.

🛡️ Features

• 🔄 Bi-directional voltage conversion (low ↔ high)
• 📊 Supports I²C, SPI, UART, 1-Wire, and GPIO signals
• ⚡ Converts between 1.8V ↔ 3.3V ↔ 5V logic
• 📏 Compact PCB, breadboard-friendly pinout
• 🧩 Easy integration with Arduino, Raspberry Pi, ESP32, STM32, etc.

🛠️ Applications

• 🤖 Microcontroller communication (Arduino ↔ Raspberry Pi)
• 📡 Sensor and module interfacing (GPS, WiFi, GSM, etc.)
• 🔌 Mixed-voltage prototyping and testing
• ⚙️ Level shifting for serial, I²C, and SPI buses
• 🏗️ Robotics and IoT development

⚠️ Notes

• ✅ Requires two reference voltages (e.g., 5V and 3.3V) for proper operation
• 📘 Designed for digital signals only (not analog conversion)
• 📦 Module color or silkscreen may vary by batch

✨ Key Advantages

• 🔒 Protects low-voltage devices from over-voltage damage
• 🚀 High-speed signal conversion for modern buses
• 🛠️ Plug-and-play with common development boards
• 💡 Cost-effective and reusable across projects
