Member #887589 / about 2 years ago / 4 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!
