SparkFun Qwiic Mux Breakout - 8 Channel (TCA9548A) - Easily Read Multiple sensors with The Same I2C Address Or Communicate with Multiple I2C Devices with Different addresses - Board only

SparkFun's Qwicc circuits might be a little more expensive, but they are well designed and work reliably.The TCA9548A bus expander is a must for integrating a large number of I2C devices, especially if you are using the random unknown quality off brand devices on here or other store fronts. The address is adjustable from severable solder jumpers. It has integrated pullup resistors for each channel. It works well with EspHome.I have each device on it's own bus, to avoid having bus contention issues and calculating pullup values. This doesn't come with cables, so you'll need a Qwiic cable set to work with it. I purchased a crimper and some female socket pins and removed the male pins from the cables to give myself some extra breakout cables.

The female end (mounted on the board) seems a little fragile and may have lacked enough solder. If the board connector was held against the board, it would work, otherwise it was a ghost problem (comes and go without any noticeable or visual reason)Otherwise, 5 stars.I do with they would improve the Arduino example for this board, seems unnecessarily confusing initially when it is really quit simple. Also, the example would not run on my DUE board, what the....!

With a Qwiic cable assortment the whole project was plug&play.
