M5Stack Pa.HUB V2.1 I2C Erweiterung Unit 1 auf 6 PCA9548A

With the M5Stack Pa.HUB V2.1 expansion unit, you can efficiently and flexibly extend your I2C communication. This small yet powerful module is based on the PCA9548AP multiplexer chip and transforms a single I2C port into six independent channels. This allows you to easily operate multiple sensors or modules with identical I2C addresses simultaneously. Switching between channels occurs dynamically via I2C commands. An integrated DIP switch enables easy configuration of the I2C address, allowing you to use multiple Pa.HUBs in the system at the same time. The six Grove-compatible ports make connecting external modules a breeze. Whether for smart sensor networks, data collection, or complex prototypes – this expansion provides a solid foundation for your projects. Thanks to LEGO-compatible mounting holes, the module can also be integrated mechanically without complications. In short: a must-have for anyone looking to get more out of their I2C bus.

Features:
I2C Multiplexing: The module is based on the PCA9548AP chip, which expands one I2C port into six independent channels.
Address configuration via DIP switch: With the integrated DIP switch, you can flexibly set the I2C address in the range of 0x70 to 0x77.
Multiple use of the same bus: You can operate several I2C devices with the same addresses simultaneously, as access is done channel by channel.
Multiple units can be cascaded: Through address switching, several expansions can be used in parallel.
