The PimoroniSpeaker pHAT crams an I2S DAC and mono amplifier, a tiny 8Ω 2W speaker, and a 10 LED bar graph all onto one teeny little pHAT. It’s the neatest way to add audio to your Pi project, and its beautiful artwork evokes an 80s boombox!
Pimoroni isn’t claiming audiophile sound quality, but it’s perfect for fun little projects where you want to add sound output – speech, notification sounds, or light music, for example.
Why not combine it with a little USB microphone to make a tiny voice-activated assistant in the style of Amazon’s Echo? Or set up a simple Flask API and send audio notifications to it from IFTTT with a simple HTTP request.
It comes as a kit, so you’ll have to solder on the female 40 pin header, and screw and solder the speaker on. Check out Pimoroni’s assembly guide for more details.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

I have this. Woo Hoo! I have it assembled and I believe I have the libraries installed, but I can’t seem to make anything happen. Are there any complete noobies guides out there to help make some music come out and the LEDs do something cool? I’ve been to the github, but just not sure what I’m missing.
