1/5/10PCS TCA9548A I2C IIC Multiplexer Breakout Board 8 Channel Expansion Board for Arduino

Description

1/5/10PCS TCA9548A I2C IIC Multiplexer Breakout Board – 8 Channel Expansion for Arduino

Unlock the full potential of your Arduino projects with the TCA9548A I2C IIC Multiplexer Breakout Board. Designed for easy integration, this compact 8‑channel expansion board allows you to connect up to eight identical I2C devices on a single bus, eliminating address conflicts and simplifying your circuit design.

Key Features

• 8‑Channel I2C Multiplexing: Seamlessly switch between up to eight separate I2C buses with a single microcontroller pin.
• Compact 2.54 mm Pitch: Standard header spacing for quick and reliable soldering or breadboard use.
• High Compatibility: Fully compatible with Arduino Uno, Mega, Nano, ESP32, Raspberry Pi, and any I2C‑capable microcontroller.
• Multiple Pack Options: Choose from 1, 5, or 10‑piece bundles to suit hobbyist or industrial needs.
• Low Power Consumption: Minimal current draw ensures efficient operation even in battery‑powered setups.
• Robust Design: Durable PCB layout and reliable component selection for long‑term reliability.

Why Choose the TCA9548A Multiplexer?

When your project requires multiple sensors, displays, or peripherals that share the same I2C address, the TCA9548A becomes indispensable. By routing each device to a separate channel, you avoid address clashes, reduce wiring complexity, and keep your PCB footprint minimal.

Installation & Quick Start

1. Mount the breakout board on your breadboard or solder it directly to your PCB.
2. Connect the VCC and GND pins to 3.3 V or 5 V power, matching your sensor voltage.
3. Wire SDA and SCL to your Arduino’s I2C pins.
4. Use the TCA9548A.h library (or similar) to select the desired channel in your code.

Applications

• Multi‑sensor data logging (temperature, humidity, pressure, etc.)
• Simultaneous control of several LCDs or OLED displays
• Complex robotics projects with multiple I2C modules
• Educational kits and prototyping environments
