Straightforward copy of Sparkfun’s SI4703 FM Tuner Evaluation Board (https://www.sparkfun.com/products/12938) with SI4703 radio and TPA6111A2 amplifier here as a much smaller add-on for Teensy or Dragonfly. The add-on is intended to be mounted onto pins 8/9/10 and 15/16/17 of the Teensy (or 8/9/10 and 30/21/20 of Dragonfly) and take power and GND from the power port at the end of the MCU. Standard 3.5 mm phone jack for headphones should allow good FM reception in a portable, battery-powered package.
