Documentation Could Be Better
The hardware works fine but finding specific example code took some time. Hardware is quality though.

Good Reception
Solid board but you definitely need a proper antenna connected to the 3.5mm jack for best results.
Q: Can I drive speakers directly from this board?
A: It is designed for headphones. For speakers, you should connect the output to an amplifier module.
Q: Does it support RDS data decoding?
A: Yes, the SI4703 chip supports RDS data decoding functionality.
Q: What type of antenna do you recommend?
A: A standard 3.5mm auxiliary cable works effectively as a dipole antenna for this module.
Q: Is this module 5V tolerant?
A: No, it operates at 3.3V logic levels. Please use a level shifter if connecting to 5V boards.
Q: What is the default I2C address?
A: The default I2C address is typically 0x11, but please check the datasheet for configuration options.
