RDA5807M FM RDS radio using the Gecko Segment LCD display. PC serial is used to display the RDS text on a pc terminal program if required (115200 baud). The two press buttons to tune up or down, touch slider to change volume. Top numeric displays frequency, bottom alpha displays station name. Ring segment displays signal level, antenna segment indicates stereo received.
