16-Channel Analog Digital Multiplexer Module – CD74HC4067 Signal Expansion Board for Arduino & Raspberry Pi

Description

The 16-Channel Analog Digital Multiplexer Module is a high-performance signal routing and expansion module based on the CD74HC4067 multiplexer IC. Designed for embedded systems and electronics applications, this module enables efficient switching between 16 independent analog or digital input/output channels using only a few control pins. By utilizing four address selection pins, the multiplexer can rapidly select and transmit signals from multiple sensors, switches, communication lines, or analog devices through a single shared signal connection. This greatly reduces GPIO pin usage on microcontrollers while maintaining stable and reliable signal performance. The module supports both analog
