Worked well to improve my I2C signals
The i2C signals improved from 3V to 4.5V and had a good stability during the clock. It allowed a 10 harness to use I2C.

These work great!
I'm impressed. The current project using a Pico to read an RM3100 sensor on about 30 feet (not inches) of CAT5 cable. The LTC4311 works as advertised and I like Adafruit's breadboard friendly design. Perfect for prototyping, suitable for a build. I'm going to order a couple more of these things

Cool little board
This thing is awesome, I actually didn't use it as an extender however I did test it with a 6 foot cable for an i2c sensor and it worked without issue. I actually used It to add pull-up resistors for a connection to an oled as the board I was using didn't have them built in. It ended up working perfectly!

A Must for Long I2C Runs
Adafruit’s LTC4311 I2C extender/active terminator will improve the signals of your I2C buss, especially where the run lengths are longer. I used one on my outdoor rover build where the total I2C run was ~30 inches. With careful wiring I had acceptable signals when viewed with oscilloscope, but with the LTC4311 installed at the end of the buss I saw improved rise/fall times and sharper signals. I was impressed. I now keep a few spares for future projects.
