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

DESCRIPTION

Unit PaHub v2.1 is an I2C multiplexer unit that uses the PCA9548AP chip solution to expand 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 polling channels). The module is equipped with an onboard DIP switch to easily adjust the I2C address of Unit PaHub v2.1, supporting multi-unit cascading to connect more I2C devices. Compared to its predecessor, it offers greater flexibility and scalability in scenarios where multiple I2C devices are used in parallel. This product is suitable for scenarios where multiple I2C devices are used simultaneously.
