5Pcs Expansion Board TCA9548A I2C IIC Multiplexer Breakout Board 8 Channel Expansion Board for Arduino

I used these multiplexers with Arduino and multiple OLED screens. They were easy to use and there were several tutorials online.

Four of out Five... that's how many actually worked.

I had to write a minor amount of code, but was WAAAY worth it. I now can have 2 installed & run one bus at 5v & another bus at 3.3 v. Makes multiple displays, sensors, etc super easy to use !! I'll be getting a lot more of these !!

Great item for extending your I2C bus for Arduino. If they work. Let me clarify, 2 out of the 5 are dead on arrival. The other 3 work fine. For the cost of them, returning them would be too much of a hassle. Spent a good 45 minutes going over my code as this was my first time using these and I thought something was wrong with the code. Finally decided to try a different one and it worked fine. Was hoping to not have to solder all the pin headers on to all 5 of them now but wanted to test the rest of them.If they work, 5 stars. But with the uncertainty of getting all 5 in a working condition, we'll drop that to 3.

Have tried to use it in combination with VL53lox sensors without any luck, Luckily i purchased the 5 pack. Maybe 1 will work out of the lot. Should have been so simple. Will contact the dealer for support. Wish me luck.
