Overview of this 74HC4051 8 Channel Analog Multiplexer/Demultiplexer Breakout Board
Introducing the 74HC4051 8 Channel Analog Multiplexer/Demultiplexer Breakout Board at the best price in India with Roboway. This arduino works as both multiplexer and demultiplexer and it allows you to route one input to 8 outputs or 8 inputs to one output. It can be used to switch sensors, buttons, audio signals, or other devices. It controlled by 3 address pins (S1, S2, S3)Â selects which of the 8 channels is active at a time.
It works with both 3.3V and 5V systems. This Arduino can pass signals in both directions, ideal for flexible circuit designs. It is allows accurate signal transmission with minimal loss or distortion. This module  useful for automation, robotics, audio, and control systems where multiple inputs/outputs need to be managed smartly.
