Defective module
The delivery was fast. Unfortunately, the module was defective and didn't properly transmit the signal.

Fast ship! Worked out of the box!
Do you have multiple I2C devices that have the same address? Don't throw them away! Get this board instead. I am using 2 SSD1306 OLEDs that have an I2C address of 0x3C

Five Stars
Nice to get multiple I2C devices up and running.

Why?
Not sure why you need these as I2C allows multiple devices on the same 2 lines. I guess if you need more then 4 devices
