Unit PaHub v2.1 is an I2C multiplexer module that utilizes the PCA9548AP chip, which expands a single I2C interface into six separate channels. This allows for various devices with identical or different I2C addresses to operate concurrently on the same I2C bus through channel polling. The module also features an onboard DIP switch, simplifying the adjustment of the I2C address for Unit PaHub v2.1, and it supports cascading connections for more I2C devices. Compared to its previous version, it provides enhanced flexibility and scalability for utilizing multiple I2C devices simultaneously. This product is ideal for projects that require the concurrent use of several I2C peripherals.
