An I2C breakout board for the RDA5807M FM radio chip, designed by ScoutMakes as a beginner-friendly introduction to electronics and wireless communications. Tune into FM stations, display RDS data (station and song names), and control everything from an Arduino or CircuitPython sketch.

The board features STEMMA QT / Qwiic connectors for solderless I2C daisy-chaining, a 3.5 mm audio jack for headphones or speakers, and a power LED indicator. It's the first FM radio breakout to support CircuitPython with STEMMA QT/Qwiic compatibility, and it's fully open-source hardware (OSHWA certified: US002137).
