8-Channel Logic Level Bi-Directional Converter Module
8-Channel Bi-Directional Logic Level Converter Module
Safely converts signals between 3.3V and 5V systems with 8 bi-directional channels. Ideal for Arduino, Raspberry Pi, ESP32, and IoT applications. Reliable, compact, and easy to use.
8-Channel Logic Level Bi-Directional Converter Module
The 8-Channel Logic Level Bi-Directional Converter Module enables safe and reliable communication between devices operating at different logic voltage levels. Designed for seamless interfacing between 3.3V and 5V systems, this module is ideal for microcontrollers, sensors, and communication modules.
Each of the eight channels supports bi-directional data transfer, making it perfect for protocols such as I²C, SPI, UART, and GPIO signals. The module automatically detects voltage levels on both sides, ensuring stable signal translation without manual configuration.
Compact, efficient, and easy to integrate, this logic level converter is widely used in Arduino, Raspberry Pi, ESP32, ESP8266, STM32, and other embedded development projects.
