The ScoutMakes FM Radio Board is a great way to learn about the world of electronics. It is an I2C breakout board for the RDA5807 FM radio chip by RDA Microelectronics. The board supports Arduino and CircuitPython. Libraries and example code are provided to help you get started.
Power pin; board includes a regulator and accepts the same power as the microcontroller logic level.
Common ground for power and logic.
I2C clock pin; level shifted for 3-5V logic with a 10K pullup.
I2C data pin; level shifted for 3-5V logic with a 10K pullup.
STEMMA QT / Qwiic connector pair carrying I2C and power to compatible boards/accessories.
Header where a piece of hook-up wire can be soldered as an antenna.
Audio output for headphones or an external speaker.
Back-side jumper that can be cut to disable power to the red on-board power LED.
