Good afternoon, from a sound system I rescued the radio receiver module that appears in the image. It has only the connection for the antenna and a flex with the connections to the main card. I was wondering if it would be possible to reuse this module independently. In the schematic identify the sound output and the power input, but the remaining connections do not. I settle for being able to change bands and tune in. I suppose that for some of the tracks that the flex has, voltages must be applied to perform the previous tasks that originally came from the main card. I appreciate if someone guides me to experiment with the module and maybe use it. First of all, Thanks.
