A fully fincationa I2C Mux
These work perfectly. I have used several, all worked. Decide whether you want the pins facing up or down

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

Very straightforward to use
I've bought this multiplexer together with HiLetgo® MPU9250/6500 9-Axis 9 DOF 16 Bit Gyroscope Acceleration Magnetic Sensor 9-Axis Attitude +Gyro+Accelerator+Magnetometer Sensor Module IIC/SPI for Arduino GY-9250 . I had to solder the heads myself. I'm not very experienced with soldering, so was a bit afraid of either overheating the module or ending up with cold joints, but it turned out pretty easy and worked ok first time round. This multiplexer is a must when you need to connect multiple sensors with same I2C address to the same MCU, for example multiple OLED screens or MPU sensors, but I have tested it with only one of each. It's very easy to program, example sketches can be found on internet, and converting existing sketches (Arduino) to work with the multiplexer is also very straightforward. I have tested it with both Arduino Nano V3.0 and ESP8285, the later using both 3.3V and 5V and all worked straight out of the box.
