Hi.
I’m wanting to use a 5v Trinket to send audio to this speaker. Is this the right amplifier for the job? Is there anything else I need?

That is the speaker they provided in the Makerverse Audio Kit I bought along with the amplifier.
Yet to use the kit, it is for the grandkids to learn on.
So I would say YES it is the right amplifier.
Cheers

Thanks @James46717
Are there Arduino compatible libraries for makerverse line products or is the focus on python?

Hi PIx,
Jim is on the money, and keen to see what you make!
PS: If you havent found a driver already there are some good audio-PWM libraries around that get the job done.

Thanks Liam.
Just to clarify, does this amplifier accept PWM or AC?

Hi Pic,
This amp is AC. PWM is a roundabout way of varying a voltage without a DAC. Before grabbing a trinket I’d check that there are libraries of the sort that can output audio. It’s not quite as easy as you would think!
Hmmm. With the synth I want to make I think I want something more robust.
This seems like the right thing.
Looks like that’s designed to work with a Pico. They cost like 10 bucks. Maybe I should rip the bandage off and learn micro-python 
.
I guess I could join the cult, find a HAL, and figure out Rust on embedded systems 
Or I could make it roll with a trinket if I use a few 74HC959s. I might be digging my own grave there 
I’ll leave this blank emoji here which I will later modify to a happy or sad face depending on whether I made the right choice.

Hi Pix,
Were you looking to play set audio files?
I’d check out the DFplayer if you havent seen it already: DFPlayer - A Mini MP3 Player | DFRobot DFR0299 | Core Electronics Australia
Hi @Liam120347
No I was thinking synthesis. Probably something simple like a cute FM synth. Something to play around with over Christmas holidays.
Do we need the R2R DAC for this amplifier to work with Raspberry Pi Pico? Makerverse 10-bit R2R DAC | Core Electronics Australia

Good news
This will work with any audio signal.
You could an alternative DAC, Analogue GPIO, or even fake an audio signal with the Pico’s PWM.
I think you will get best results with a DAC of some kind, but it doesn’t have to be the Makerverse 10bit.
With that having been said I’ve recently had a lot of fun faking the signals with some 500uf capacitors and a digital GPIO pin on a raspberry pi zero (which is similar to the pico). The results are mixed; little bit of that 1990s punk rock distortion. The maker-verse amplifier handled all of my shenanigans like a champ 
Does that answer your question?
