Adafruit Speaker Bonnet for Raspberry Pi
learn.adafruit.com
This Bonnet uses I2S a digital sound standard, so you get really crisp audio. The digital data goes right into the amplifier so there's no static like you hear from the headphone jack. And it's super easy to get started. Just plug in any 4 to 8 ohm speakers, up to 3 Watts, run our installer script on any Raspberry Pi, reboot and you're ready to jam!

See title. I’m thinking of picking this up to power a pair of speakers but am currently powering my Pi using the GPIO pins. If I install this, will I no longer be able to power the Pi that way? Will I have to use the MicroUSB?

      Oh yeah, that would be perfectly fine. It would power both the pi and audio board according to this schematic.

        Thanks I think I’ll do that

      Soldering to those power pads should be fine. You really should keep tabs on your current draw though. If anything, you might need an extra capacitor or two across different points on the main power rails. What may happen, depending on a few different conditions, is that if you get a hard bass hit, your pi might reboot due to lack of power.

      Everything you are using is overbuilt, for the most part. Just be mindful of where the most power is being drawn and if the current source you are pulling off of is regulated or not. (Any LDOs provide clean’ish power rail for the processors and other ICs, so if the supply voltage is correct, tap before LDOs, not after, for a higher current load.)
