The SoundDuino Arduino sound shield is capable of working with voltages from 3.3v to 5v and if you use the other Arduino boards, the only pins that you require are GND, VCC, RX, TX.

Using it is as simple as picking it up from the Arduino IDE. If you are looking for an RDS-enabled radio to test out your QN8066 design, you wouldn’t do too bad with this Gameboy cartridge receiver.
