Quick question if I may: is it possible, using additional electronics, to get an audio signal from an RPi Zero (based on the 3+ model). If so, which pins do I need, is the output an analog audio signal (that just needs amplification) or PWM. There's only 1 speaker available, so a mono output suffices.
Reason for asking: I'm working on a project and the Zero would be ideal space-wise although the original design did call for a RPi 3B+ model to be used. Besides, the Zero is cheaper, which helps the cost/benefit analysis
