Analog & Digital Multiplexer Breakout Board Modules - In Stock at Communica SA

Find the Right Multiplexer Breakout for Your Application

Multiplexer (MUX) breakout board modules are essential in projects where you need to expand input/output capabilities-whether you're switching multiple sensors, reading assorted analog signals, or routing digital controls. At Communica, one of Southern Africa's largest distributors, you'll find a comprehensive range of analog and digital MUX boards suitable for student builds, industrial automation, and embedded system development.

Our collection covers modules based on popular chips such as the CD74HC4067 (16-channel analog/digital), 74HC4051 (8-channel), and CD4052 (dual 4-channel), along with digital-only multiplexers/DEMUX boards for simplifying digital I/O expansion. These modules save pin count and simplify wiring for microcontroller, PLC, Arduino, or Raspberry Pi projects.

Why Use Multiplexer Breakout Boards?

• Expand microcontroller analog or digital input/output channels
• Efficiently multiplex many sensors (e.g., potentiometers, buttons, analog sensors) onto a single pin
• Optical, audio, and signal routing in automated test setups
• Save on MCU pin requirements in space- or budget-constrained projects

Choosing the Right Analog or Digital Multiplexer Module

When selecting a multiplexer breakout, consider:

• Analog vs Digital: Stick to analog MUX ICs for sensor signals (potentiometers, temperature, audio). Digital-only chips work for high/low logic or switch arrays.
• Channel Count: For example, a CD74HC4067 handles up to 16 channels, great for monitoring many inputs from one microcontroller pin.
• Voltage Compatibility: Most breakouts support both 3.3V and 5V logic, but always check brand/datasheet for specifics.
• On-Board Pull-Ups/Downs: Some modules integrate resistors for easier hookup - useful in classroom or test bench setups.

Example Use Case: Signal Expansion on Arduino

Suppose your Arduino UNO has 6 analog pins but you need to monitor 12 sensors. By connecting a CD74HC4067 breakout (16-channel), you can scan all sensors using a single analog input and 4 digital select lines. The benefit: save PCB space and reduce the number of wires running to your board.
