 This is me testing out my prototype for the audio BFF board. BFF boards are these little microcontroller add-on boards that plug into a QT-Pie or shell breakout microcontroller to add more capability. So we've already made one with a microSD card and we also made one with an I2S amplifier and I've got one that mixes them both together so we've got microSD and amplifier which means it's perfect playing audio through this picoblade to up to a three watt speaker. So I plug it in, I've got a little bit of circuit python code running on this that'll play all the WAV files that are on the microSD card in order. And then some Taylor Swift going, got some white stripes going on, and then finally the happy song by Imogen Heap. So very good for making audio playing projects, very, very tiny. It's all in one and it's coming to the Adafruit shop real soon. Bam!
