ACEIRMC 10pcs CD74HC4067 16-Channel Analog Digital Multiplexer Breakout Board Module for Arduino 2V-6V Microcontroller 16 Device RX Lines

This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067. This chip is like a rotary switch - it internally routes the common pin (COM in the schematic, SIG on the board) to one of 16 channel pins (CHANxx). It works with both digital and analog signals (the voltage can’t be higher than VCC), and the connections function in either direction.. Analog output: DIG;Channel control: S0-S3. This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067.. To control it, connect 4 digital outputs to the chip’s address select pins (S0-S3), and send it the binary address of the channel you want. This allows you to connect up to 16 sensors to your system using only 5 pins!
