Do you have sample Pico code and wiring for this?

Hi Claire,
I found this library to work well with this driver: GitHub - danjperron/PicoAudioPWM: PWM audio on pico with 8KHz stereo wave file
Here’s a quick wiring diagram for the product, I’d recommend going with Enclosed Speaker - 8 Ohm, 5 Watt | Core Electronics Australia for speaker

Please could you tell me what the maximum output power of the amp is?

Hi Jim
Welcome
As with any Class D amplifier that will depend on input DC voltage (2.5 - 5.5V) and speaker impedance (4Ω or 8Ω).
There should be a chart with that info but I note in this case there is none. You might get some info with the IC data sheet if you can find out what IC is used.
Cheers Bob

Hi Jim,
At 4Ω the output is 3W.
It uses a PAM8406. I’ve updated the store page with that info and the datasheet.

Hi Jim
Now we know what the IC is (thanks Jack) the data sheet tells us this.
This should answer your question.
