A new BFF with I2S audio amplifier

Introducing a new BFF for your tiny audio projects! This sketch-of-a-board adds a MAX98357 3W I2S amplifier to your favorite QT Py or Xiao boards.

The pins have been picked to work with RP2040, ESP32 series, and nRF52840 boards. For SAMD21 boards, some pin adjustments may be necessary.

Maybe we’ll make ones with a microSD card socket as well? Let us know your thoughts and other BFF ideas you have for us to explore.

    Please add a MEMS microphone, so we can play with wake-up words.
