Update
Using the post from “Ashthespy” in this thread I was able to get the GPIO plugin installed AND get the shut down / power up function to work perfectly! Upgrade to Volumio 3 - GPOI plugin missing - #6 by gkkpch
I’m very happy with the way the button looks and performs. I originally was going to use a 16mm switch but it looked too big in relation to the unit so I went with a smaller 12mm switch I also had on hand.
I also forgot to show it in the above images but Vincent includes a great feature in a removable, acrylic window for easy access to the SD card.
Comments/critiques welcome. Let me know what you think.
Here it is finished.
