The M5Stack PaHUB Unit is a 6-port I2C port expander for M5Stack kits. It is equipped with 6 Grove connectors and allows you to connect several devices with the same address to one I2C bus. It is based on the PCA9548APW chip that communicates with the evaluation kit via the I2C interface. Due to the fact that the expander address can be modified, it is possible to connect up to 8 devices on one line. The module will be used in projects where the number of I2C ports of M5Stack sets is insufficient or there are devices with the same address. Full documentation is available on the product page.
