The 7Semi UART Mux Demux Breakout Board is a compact and highly efficient solution designed to simplify UART communication management in embedded systems. Built around the reliable SN74LV4052 dual 4-channel analog multiplexer/demultiplexer, this breakout board allows developers to connect and switch between multiple UART-enabled devices using a single microcontroller UART interface.
In projects where UART ports are limited—such as Arduino, ESP32, STM32, Raspberry Pi, or other microcontrollers—this board provides an elegant way to expand connectivity without additional hardware UARTs. By using simple control signals, users can dynamically select which UART device is active, enabling seamless communication with GPS modules, GSM modems, sensors, displays, debug consoles, or multiple peripherals.
The board supports a wide operating voltage range from 1.65V to 5.5V, ensuring compatibility with both low-power logic systems and standard 5V development platforms. One of its key advantages is the ability to handle both analog and digital signals, making it suitable not only for UART switching but also for general signal routing applications.
Designed with prototyping and development in mind, the 7Semi UART Mux Demux Breakout features clearly labeled pins and a breadboard-friendly layout, allowing for quick integration into test setups and final designs. Its low power consumption and fast switching performance make it ideal for IoT devices, robotics, industrial automation, and communication-intensive applications.
Whether you are optimizing hardware resources, reducing PCB complexity, or building scalable communication systems, the 7Semi UART Mux Demux Breakout Board offers a cost-effective, reliable, and flexible solution for managing multiple UART connections with ease.
Features
- Effortless UART Switching: Control the flow of your UART signals with ease, switching between four outputs seamlessly.
