Mu is a simple code editor that works with the Adafruit CircuitPython boards. CircuitPython driver for the TCA9548A I2C Multiplexer.
Theres pages for overview, pinouts, CircuitPython, Arduino and download resources.
It is pulled HIGH by default, so you can just leave it as it is.
.
The multiplexer is a cheap copy of the Adafruit TCA9548 module TCA9548A I2C Multiplexer ID 2717 6.
If you need to have up to 8 multiplexed devices, check out the 8-channel TCA9548.

UPC P2717.
You can use this multiplexer with any CircuitPython microcontroller board or with a computer that has GPIO and Python thanks to AdafruitBlinka, our CircuitPython-for-Python compatibility library.
65- to 5.
It&39;s written in Python and works on Windows, MacOS, Linux and Raspberry Pi.

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDASCL pins".
The multiplexer supports both normal (100 kHz) and fast (400 kHz) I2C protocols.
