General description
The Q9 module is the best price/performance DAB+/DAB/FM/RDS radio module in the current radio markets. The Q9 integrates all the necessary interfaces to enable radio manufacturers easily and effectively to implement radios or embedded audio systems. The manufacturers only need a power supply, display, keypad, audio amplifiers and speakers to implement a fully functional DAB+/DAB/FM/RDS radio or using Q9 as a radio block of an audio system.

Q9 operates in master mode or slave mode with the control of an external MCU.
