This is a lovely little amp well suited to driving a low impedance speaker. I have it working on a pi zero w with a richard allen baflette speaker.
Just be sure to solder to the pi gpio pins. (The friction fit really isn’t good enough). And the speaker terminals are also flaky. The makers should fit better ones or just leave solder tags.
Anyway. Can’t complain too much at the price. Highly recommended.
