Your cart is empty.- 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. 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 (see the datasheet for details). This allows you to connect up to 16 sensors to your system using only 5 pins.

I would rather have cmos IC’s. These must be run on 5 volts. I didn’t notice this when I ordered them.

This multiplexer works seamlessly with any electronic microcontroller project. One thing to note is that this operates at 5V. Other than that, it is extremely straightforward to use.

These are standard basic MUX boards to add inputs to any IOT device. It uses 5V ICs so you will need to make sure it's compatible or use a voltage converter to change from 3.3V to 5V. Works well, just understand it use case.
