2-Channel Logic Level Converter – 3.3V to 5V TTL Bi-Directional

The 2-Channel Logic Level Converter allows seamless voltage translation between high and low logic levels. Whether you’re interfacing 5V and 3.3V devices or working with 2.8V to 1.8V systems, this module provides a safe and efficient way to ensure compatibility between different logic levels.

Key Features

✔ Bi-Directional Conversion – Converts signals in both directions: 5V↔3.3V, 2.8V↔1.8V
✔ Safe Voltage Shifting – Protects low-voltage devices from damage by reducing signal voltage appropriately
✔ Multiple Device Compatibility – Works with Arduino, Raspberry Pi, STM32, ESP8266, ESP32, and other microcontrollers
✔ Plug-and-Play Design – Simple connection with clearly labeled HV (high voltage), LV (low voltage), and GND (ground) pins
✔ Ultra-Compact & Lightweight – Small 15mm x 15mm form factor, perfect for embedded projects

How to Use

1️⃣ Connect HV Pin to your high-voltage source (e.g., 5V)
2️⃣ Connect LV Pin to your low-voltage source (e.g., 3.3V)
3️⃣ Connect GND Pin to your system’s ground
4️⃣ Use the bi-directional channels for logic signal conversion between different voltage levels

💡 Perfect for interfacing 3.3V sensors, LCDs, I2C devices, SPI peripherals, and more with 5V microcontrollers!

Package Includes:

✔ 1 x 2-Channel Logic Level Converter (3.3V↔5V TTL)
