Nozzle Head 1.75 0.3 MK8 3D Printer Extruder

Industrial Abrasive Scourer Pad 150x50mm Laminated Copper Plate PCB features:
Industrial abrasive scourer for laminated copper plate Cleaner for cleaning the laminated copper plate. Perfectly removes impurities such as oxides, sulfides and other similar establishments, as well as polished surfaces so that the copper substrate is better prepared.
It is also ideal for removing the remains of enamels, lacquers and other materials used during the creation of PCB tracks.

A multiplexer of this type actually only acts as a switch 16 to a 1.
The 4 digital pins are used to set high or low, (binary Y0-Y15) to determine which input pin is connected to pin "Z".
The control input S0-S3 is set to low "logic level 0", the signal C0 is connected to the output Z. Multiplexer 16 Channels CD74HC4067 MUX/DEMUX features:
- Based on chip CD74HC4067
- Analog signal input: Y0-Y15, 16 channels
