The 7Semi TCA9548A I2C MUX Module is a useful board that helps you connect multiple I2C devices to one controller. It is mainly used when you have devices with same I2C address and want to use them together. This module allows you to switch between 8 different I2C channels easily using software. It is simple to use and works well with sensors, displays, and other I2C modules. Compact size and easy connection make it perfect for hobby and advanced projects.
Features:
• 8 Channel I2C MUX: Connect up to 8 I2C devices
• Address Conflict Solution: Use multiple same address sensors
• I2C Controlled Switching: Select channel using software
• Reset Pin: Easy reset and control
• Wide Voltage Support: Works from low to standard voltage levels
• 3.3V Compatible: Suitable for modern microcontrollers
• Stable Communication: Reliable I2C signal switching
• Compact Design: Easy to use in small projects
• Multi-Device Support: Works with sensors, displays, EEPROM, etc
• Ideal Use: IoT, robotics, sensor arrays, embedded systems
