12PCS CD74HC4067 16-Channel Analog Digital Multiplexer Breakout Board Module 2V-

This is a breakout board for the very handy 16-Channel Analog/Digital Multiplexer/Demultiplexer CD74HC4067.Function: Use 16 ADCs to collect 16 analog signals.Use the CD74HC4067 16-channel analog signal switch..Analog Input: C0-C15 16 channels; Analog output: DIG; Channel Control: S0-S3This 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.A method for controlling the motor, lights, LED, DC motors, micro-pumps, solenoid valves, etc., very convenient.
