    Received as expected, yet untested, great to save pins/cables with devices that have same address, also could provide that other devices are reachable if one on other bus behaves bad.

    Awesome allows to overcome the limitation of I2C interfaces with modules on the same address, offering 8 interfaces in total. We can put more sensors in.

    Well packaged and good delivery time, considering Spring Festival (25 calendar days from order). This module is a great way of running multiple (non-concurrent) two-wire buses on an MCU. You write a control byte to an IIC port to select which of 8 slave ports will be active. Adafruit have a good tutorial on how to use this module. This is a useful module and I am happy to recommend it.

    Bought to upgrade my thermodynamic VMC with a gas-free air conditioning system. These interface being to position new pressure/humidity/temperature sensors in the beast:-)
