M5Stack I2C Hub 1 to 6 Expansion Unit v2.1 with DIP Switch (PCA9548A)

M5Stack I2C Hub 1 to 6 Expansion Unit v2.1 with DIP Switch (PCA9548A)

€8,20

Unit PaHub v2.1 is an I2C multiplexer unit utilizing the PCA9548AP chip, capable of expanding a single I2C interface into six channels. By selecting different channels, it allows multiple devices with the same or different I2C addresses to coexist on the same I2C bus (switching via channel polling). The module features an onboard DIP switch for easy adjustment of the Unit PaHub v2.1's I2C address, supporting multiple-unit cascading to connect more I2C devices. Compared to its predecessor, it offers greater flexibility and scalability in parallel I2C device usage scenarios. This product is ideal for applications requiring simultaneous use of multiple I2C devices.

 

 

Features

  • I2C HY2.0-4P PORTA expansion
  • Allows multiple-unit nesting
  • 6 extended Grove ports
  • DIP switch for I2C address selection
  • LEGO-compatible holes
