TCA9548A I2C Multiplexer Module - With Arduino and NodeMCU

Did you ever get into a situation where you had to wire up two, three or more I2C Sensors to your Arduino just to realize that the sensors have a fixed or same I2C address? Moreover, you cannot have two devices with the same address on the same SDA/SCL pins!
So, what are your options?
Put them all on the TCA9548A 1-to-8 I2C multiplexer to get them all talking to each other on the same bus!
The TCA9548A Breakout enables communication with multiple I2C devices that have the same address making it simple to interface with them.

Ummm... THAT's how videos should be. Very informative, volume is correct, no stupid music, great visualisations like transitions and illustrations... it's a very well done video. Other than his accent which is a bit hard to understand (captions solve that) it's a near perfect example of what I think tutorials should be striving for. He even has a little timeline so you can skip to parts of the video. It's a little more techie and in depth than most folks would need, but the time line is right there to skip if you don't need that level of detail.

dude, your video was the best on I2C till now. keep up the good work...cheers mate.

[maartenvd]

Thank you! Very well explained to enough level of detail without going too deep into things.

Great one. I learned everything I needed about TCA9548A.

[robertlongoria]

Thank you, opened my eyes to may i2c properties.

[shiftyjesusfish]

trojan miner baked right into that nice.

[emimix]

Very useful and easy to follow video...thanks

Very nice video explanation. But I got confused in the last section. @ 01:30 you said you will be explaining advantages and disadvantages of TCA9548A but @ 08:35 you actually explained advantages and disadvantages of I2C communication. Please correct me if I am wrong

[marvinsernande]

This is awesome! May I ask if I2C communication and TCA9548A is okay with long wires? Thank you

[donnysdp]

Nice explanatation sir! Truely understandable! But i have 1 question.

Does the I2C Multiplexer Module has a library to install? or i doesn't require to install any library?

Segment at 4:32 Is interesting. I am bookmarking this with this comment.

[cookone]

I'm impressed
So i am going to subscribe

Great video. Thanks
Question (i saw this in video, but just want to clarify)
I have found in TI datasheet that the chip "allows voltage-level translation between 1.8-V,
2.5-V, 3.3-V, and 5-V buses"
will it work with different Vcc's or only that it supports all types of Vcc's 1.8-5? i have both options of I2C devices 5V Vcc and3.3V Vcc. can i use this device without logic level converter?
Thanks

Hello, great video 😁,

I'm a beginner and I have a question :
Can the TCA9548A multiplexer work with The MCP23017 GPIO Expander?
Thank you in advance for your precious support 😄

Cordially.

Muito bom! Adorei a forma como você fez o vídeo! Me inscrevi!

[PavanMuppala]

very nice explanation bro, can I use this module to measure my battery pack connected in series where each cell ranges (1.6v - 3.3v) because I can not use audrino directly cus it is having a single ground pin.

[hamadrd]

Very good Tutorial, I Love it, your English is GREAT and You made it easy for us to understand
However, total I/Os current is 200ma for arduino, So do you know how much current drawn out of arduino pin to this I2C chip? And do the expanded pins current in total affect the Arduino pin if it is more than 40ma?

[TheRainHarvester]

Great topic! Does it cost less than another nano? I find myself just adding another nano or Stm32f103c8t6 sometimes for more gpio. I wish they had a cheaper solution.

[pawankumarsingh]

Awesome, can we receive multiple sensor data & check that data on blynk or MIT. I m working on a project, we would be helpful to me.

So you didn't use pull up resistors in your demo, are they required or are the pull ups on the TCA9548A board shared through all its ports?
