4-Channel Logic Level Converter – Bi-Directional
📝 Overview
The 4-Channel Bi-Directional Logic Level Converter is a compact module designed to safely interface digital devices operating at different logic voltage levels. It converts signals between low-voltage and high-voltage systems, making it suitable for connecting microcontrollers and sensors with different operating logic levels.
⚙️ Key Features
Supports 4 independent logic signal channels.
Bi-directional voltage level conversion.
Supports interfacing between 3.3V and 5V logic systems.
Separate high-voltage (HV) and low-voltage (LV) sides.
Compatible with digital signals, including I2C, UART, and SPI, depending on operating conditions.
Compact design for breadboard and PCB projects.
No programming required.
