Pimoroni 라즈베리 파이용 스피커 pHAT
(Speaker pHAT)
개요
- 본 제품은 파이 제로용 스피커 pHAT보드입니다.
- I2S DAC, 모노 앰프, 8오옴 2W 스피커, 10 LED 바그래프, 이 모든 것을 작은 pHAT 보드에 모두 담아낸 보드로 라즈베리 파이에 오디오 기능을 추가할 수 있습니다.
- 최상급의 음질을 자랑하는 것은 아니지만 사운드 출력이 필요한 프로젝트에 쉽게 사용가능합니다.
- 키트형태의 제품으로 조립이 필요합니다.

문서
- 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 our assembly guide for more details.
- We've put together a handy one-line installer that will get everything set up in a jiffy! Our 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. Find details of how to run the one-line installer in the Speaker pHAT GitHub repo.
Our software does not support Raspbian Wheezy.
Notes
- The DAC sums the two audio channels to mono, rather than just outputting one channel or the other, meaning that you get both channels of audio out of the single speaker
- The dimensions of an assembled Speaker pHAT are (height does not include the female header): H 10mm x L 65mm x B 30mm. The speaker itself measures: H 6mm x L 40mm x 20mm.
- Speaker pHAT won't fit on top of a Pibow Coupé or Pibow Zero due to the height of the speaker, and you won't be able to use a heat sink for the same reason.
- 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.
