Find Multiplexer Breakout Boards for Your Project

Multiplexers play a crucial role in connecting multiple input signals to a single microcontroller I/O, enabling efficient sensor expansion, keypad integration, data logging, and logic control without redesigning the core circuit. Whether you're prototyping with Arduino, integrating into industrial PLCs, or designing compact measurement systems, the right analog or digital multiplexer breakout module simplifies your build and maximises flexibility.

Analog vs Digital Multiplexer Modules

Communica stocks a full spectrum of multiplexer modules, from basic CD74HC4067 breakout boards for up to 16:1 channel expansion to robust logic MUX solutions for industrial and educational builds.

Why Use a Multiplexer Breakout Module?

• Rapidly expand inputs or outputs on microcontrollers/PICs/STM32 systems
• Simplifies wiring and breadboarding for hobbyists and students
• Enables addressable sensor arrays, keypads, and signal routing for automation
• Facilitates lab and prototype signal selection for measurement equipment

Multiplexer breakout boards often feature clearly labeled pins, onboard pullup resistors, and input protection-speeding development and increasing circuit reliability. For industry, choose boards with robust screw terminals and clear indication for diagnostic work.

Specifying the Right Module for Your Application

• Channel count: Typical breakouts support 8:1, 16:1, or smaller.
• Voltage compatibility: Match logic levels (3.3V/5V) to your system.
• Bandwidth: Analog muxes have frequency limits-consider this for audio or fast signals.
• Form factor: Breadboard, screw terminal, or module mount options.
• IO protection: Needed for industrial or lab environments.

How to Request a Multiplexer Quote and Compare Options

At Communica, the process is streamlined for engineers, students, and procurement teams. Whether you need a single development board for rapid prototyping or supply for a lab, you get quick responses and local support in ZAR. Here's how to proceed:

1. Browse Sensors & Semiconductors or Prototyping.
2. Add preferred multiplexer modules (IC type, channel count) to your quote request-include special instructions like "require VAT invoice" or "Samrand pickup" if needed.
3. The Communica team will confirm stock, lead time, and delivery/collection options. Bulk discounts may be available for teaching/lab use.

Example: Connecting a 16-Channel Analog MUX to Arduino

Arduino Pin: D2 -> MUX S0
Arduino Pin: D3 -> MUX S1
Arduino Pin: D4 -> MUX S2
Arduino Pin: D5 -> MUX S3
Arduino Pin: A0 -> MUX SIG (common output)

This setup allows you to scan multiple sensor voltages in code, reducing the number of pins used. For digital muxes, connections are similar but limited to logic signals.
