HiLetgo PCA9548A TCA9548A I2C IIC Multiplexer Breakout Board 8 Channel Expansion Board for Arduino

HiLetgo PCA9548A TCA9548A I2C IIC Multiplexer Breakout Board 8 Channel Expansion Board for Arduino

Q: Is this compatible with a Raspberry pi?

The simple answer is yes. We use it as an I2c multiplexer to access an array of magnetic sensors which cannot be assigned to different I2c addresses. Since there are two i2c channels on Raspberry Pi 3B's and 4b's, we run two different sensor arrays on a single Pi, or each array being run by its own Pi, depending on how intense the data acquisition volume is required.

Fast ship! Worked out of the box!

The media could not be loaded. 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

Defective module

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

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
