My students have been working with the Metro Express M4 for years, and I would like them to be able to play music from the board.
I saw the Adafruit STEMMA Speaker - Plug and Play Audio Amplifier, and I’m wondering if I can get this to work with my Metro. Has anyone done this?
The learning examples only show CircuitPython Express board code and wiring.
Thoughts?

Re: Metro Express M4 with Adafruit STEMMA Speaker - Plug and
It should generally work the same, as long as you can make the connections.
Start by using the same general wiring:
https://learn.adafruit.com/adafruit-ste ... aker/usage
on the Metro:
* BLACK to GND
* RED to 3.3V
* WHITE to A0 (or A1)
And then to generate the sounds, start here:
https://learn.adafruit.com/circuitpytho ... -audio-out
The code examples there appear to use A1. You could either change the code to A0, or try wiring speaker to A1.
