Buy wholesale multiplexer breakout modules for engineering, industry, or labs. Choose from analog & digital types, bulk deals, and same-day branch pickup at Communica.
Choose analog and digital multiplexer modules for varied voltage, channel, and logic requirements.
Benefit from wholesale pricing, VAT invoicing, and local pickup options for larger requirements.
Access modular boards from global brands and cost-effective ranges, ready to ship from Communica branches.
Multiplexer (mux) breakout boards are essential tools in modern circuit prototyping, testing, and scalable product development. By enabling multiple signals-either analog or digital-to efficiently route through a limited set of microcontroller pins, multiplexers simplify wiring, reduce GPIO usage, and streamline complex designs. For South African engineering teams, university labs, or volume integrators, sourcing these modules wholesale ensures reliable supply and cost savings.
Breakout boards often provide soldered or pin-header interfaces, logic voltage level translation (3.3V/5V), power decoupling, and clear labeling for quick integration with popular microcontroller platforms like Arduino, Raspberry Pi, and ESP modules.
| Module Type | Channels | Logic Voltage | Analog/Digital | Typical Chipset/IC |
|---|---|---|---|---|
| 16-Channel Analog MUX | 16:1 | 2V-6V | Analog | CD74HC4067/HEF4067 |
| 8-Channel Analog MUX | 8:1 | 2V-6V | Analog | 74HC4051 |
| 4-Channel Digital MUX | 4:1 | 3.3V/5V | Digital | 74HC157 |
Connecting a 16-channel CD74HC4067 break-out to a microcontroller with just 4 address lines allows up to 16 analog sensors to be read using a single ADC input. This is particularly useful for educational lab kits, student projects, and monitoring applications in the industrial sector.
