General description
The Q8r+ module is the best price/performance DAB+/DAB/FM/RDS radio module in the current radio markets. The Q8r+ 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 Q8r+ as a radio block of an audio system.

Q8r+ operates in master mode or slave mode with the control of an external MCU.
