MANY years ago, we put together a 500 sensor array for monitoring temperatures, etc. in a turbine powered,
electrical generator set, under test. It took multiple Hewlett Packard, HPIB bus multiplexers, at a cost of MANY
thousands of dollars to get the results we needed. Using the Arduino ecosystem today, we could do the same
thing for a fraction of the cost.
All I can say to the SparkFun team is - Keep Innovating!

When using TCA9548A, should I remove the pull-up resistors of the modules I have connected?
