## Questions & Answers

**Q: Can the analog-digital breakout board be set up to use the aref (analog reference) pin on the arduino with which it is communicating?**
A: The AREF pin on the Arduino is an input pin, not output.  You can still use the Arduino and the Analog-digital breakout board work at the same 5V voltage and have a different AREF, let's say 3.3V.  AREF of 3.3V means that the Arduino will translate 3.3V as the max value of 1024.  By default, AREF pin is open and Arduino assumes a value of 5V.  If you apply a different AREF value to the physical pin, you need to use AnalogReference() to set it to use the EXTERNAL value and not the DEFAULT.

**Q: what is the bit-rate of the A/D?**
A: This is not an Analog to Digital converter.  It is based on the CD74HC4067 digitally controlled analog switches.  You can redirect any of the 16 signals to a common output.  Propagation delay @ 5V is 6ns

**Q: Will this increase the number of digital pins on an Arduino nano?**
A: No, this board only multiplexes (switches) 16 signals to one (input or output).  To increase the digital pins, you need a port expander.  Search for 16 Output I/O Expander Breakout - SX1509
