    Don't always trust the arduino website. It's very outdated and often incorrect. You could try compiling some example code that uses SPI. If it compiles, the statement from the arduino site would be incorrect. Commented Apr 20, 2016 at 9:23
  • You can always connect your logic analyser or oscilloscope to the SPI pins and actually look at what is happening on the pins... You do have the basic test tools you need to do electronics, don't you? hackingmajenkoblog.wordpress.com/2016/03/23/… Commented Apr 20, 2016 at 11:18
  • @Gerben Although I did not try to run one of their samples, I did run my own code (the same code that works on the Uno) and double-checked the wiring. While the compile and build were fine, the SPI device did not respond with any data, nor could I see any other sign that it was working. Commented Apr 20, 2016 at 13:40
  • I thought this was a purely theoretical question. Showing your wiring and your code would be helpful. Commented Apr 20, 2016 at 17:23
  • @Gerben I am asking it theoretically, having been prompted (as mentioned) by seeing a certain behavior in reality. I would like to keep this question away from my specific test and focus on the theoretical situation: Does the Nano support SPI, and is there anything that must be done differently on the Nano to use it? If the answer is that it does support SPI out-of-the-box, I will then investigate on my own why I was unable to get it to work. Commented Apr 20, 2016 at 19:02
