Our pirate friends at Pimoroni have taken the I2S mono DAC and amplifier that they used on Speaker pHAT and Picade HAT and added a second one for stereo goodness. pHAT BEAT gives you high-quality, digital, amplified, stereo audio and 16 beautiful little RGB LEDs, in two rows of 8, that are ideal as a VU meter, and 6 buttons to control your audio. There's a nifty little DIP switch on the bottom of the board that lets you select either mono (left and right are blended through both channels) or stereo playback. The clip-in terminals make it super-simple to wire in your speakers.
