Nice solution for multiple I2C devices - Teensy/Ardruino
Created a board with 1.5k pull-ups on each scl & sda 1-7... I've got 2 AS5600's, LCD 20x4 running @ 5v, 24l256, and INA 226...they work great...1.5-2.2k pull-up resistors work fine to 400k clk on wire. No issue switching channels...give the enough microsecond maybe 50 to settle before reading/ writing and also after done...

Good Mux
I have many of these, all worked.They do exactly what they are supposed to do.

Exactly what I needed
I was working with a project that used four different I2C devices, and two of the devices shared an address with no way to change it, on top of that the small MCU I was using only had enough GPIO to handle two of them. After some research and hunting I came across these boards and they do exactly what I need, I have all four of my devices happily running using a single I2C connection on my board, including the conflicting addresses. Google was very friendly about finding documentation that explained exactly what I needed to do.Just make sure you get those pins soldered in nice and solid, one loose pin can make the whole thing get weird.

Can really extend the I2C bus.
Works great for large arrays of I2c devices. It has a selectable 3 bit address which means that 8 of these extenders can be used with only 1 Master with two wires (Plus power and ground) . That gives a ridiculous 512 device count that can be controlled. And if the i2c devices are 8 pin breakout modules, you then have 4096 individual input/output lines. (8x8x8x8) Considerably more than the few dozen on the Pi or Arduino.More practically, one of these will allow 8 chains of 8 I2c devices to be controlled. (Assuming that the controlled devices don't have a single hardwired address.) But even with those fixed address modules, 8 can be controlled with this expander.FYI. When you turn on a channel, remember to turn it off before you move to another, unless you want to control several devices in parallel. This chip will happily let you write to all 8 chains at once - probably not what you intend to do.
