Module with 16 channel CD74HC4067 multiplexer allows you to connect up to 16 signals to a single analog output. The system can work as a demultiplexer and work with digital signals. This means that with a single contact you can display up to 16 signals or you can connect 16 sensors to one terminal. The module is supplied with the voltage from 2 V to 6 V.
Outputs are solder fields for soldering goldpin connectors (2.54 mm rster). Thanks to them, it is possible to connect the system with the breakout board or the main module (for example, STM32Discovery or Arduino) via wires.
The set does not contain a goldpin strap, it can be purchased separately.
System multiplexer/demultiplexer operates as a switch. Sends a signal from the common output (labeled COM - in the diagram, SIG - on-board) to one of 16 channels (CHANxx). It can also work in the opposite direction, that is, to transmit a signal from one of the 16 channels on the output. The module works for both digital and analog - the voltage value must not exceed the power supply (VCC).
To control the multiplexer you need to connect digital pins S0 - S3 and to specify the corresponding binary address. Details in the documentation .
The module also works with digital signals. This means that you can use it to switch the communication interfaces. For example, by connecting one output serial TX you can communicate with 16 receivers RX. Similarly, with the I2C bus, SPI and others.
