I found such modules (TEA5767) in a fabric MP3 player. I played with them using Arduino for control and I was impressed by the sound they deliver. I decided to make standalone radio based on the module. I wanted to make it as small as possible and I have chose to use 8-pin Atmel Attiny85 nicrocontroller in SO8 package. The main challenge was that the Attiny85 does not directly support the I2C protocol used by the TEA5767 module, so I had to rewrite some libraries to make this possible.
High quality FM radio receiver based on the TEA5767 chip, controlled by Attiny85. The board is small and can be used for DIY project having FM radio. The board has an SPI interface and the microcontroller can be re-programmed as you desire. This also makes the product a development board for TEA5767 module. If you wish, the radio can be offered as a DIY kit.
Update: Newer version exist now - to decrease the power consumption the stereo indicator LED was removed. A power switch was added. Please, ordering the radio indicate which of both versions you prefer. If not selected - a random or currently available version will be sent.
