Details

Although the speakers don’t offer exquisite sound quality, thanks to their compact size they’re perfect for little projects where you want to add sound output - speech, notification sounds or light music etc.

You can also combine it with a USB microphone to make a small 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.

Features

  • I²S audio DAC with 3W mono amplifier (MAX98357A)
  • Default output of 0.45 W / 26.5 dB
  • 8 Ω 2 W Mylar speaker
  • Routed holes to channel sound
  • 10 bright white bar graph LEDs
  • SN3218 LED driver chip
  • Speaker pHAT pinout
  • Compatible with all 40-pin header Raspberry Pi models
  • Female header and speaker require soldering (includes a piece of bare wire to solder the speaker)

Kit includes

  • Speaker pHAT
  • 8 Ω 2 W Mylar speaker
  • 2 × 20 pin female header
  • 5 cm 24AWG bare wire
  • 4 × M2x8 black nylon bolts
  • 8 × M2 black nylon nuts

 In the Speaker pHAT GitHub repository you’ll find a one-line installer with which you’ll start with your projects very quickly. The installer configures ALSA to output sound through the DAC on Speaker pHAT, and installs a custom plugin to display sound level on the bar graph LEDs.

It's important that you use four of the included eight nuts as spacers to space the speaker slightly away from the PCB. Not doing this, and having the speaker cone touching the PCB, can result in sound degradation and even damage to the speaker.
