7V-18V MP3 Bluetooth Decoder Board Car MP3 Player Radio Auto Stereo Audio Module Support MP3/USB/TF/FM/BLUETOOTH/Remote Control/ Speaker 2*20W

Show Original Delivery was very fast. Even earlier than promised. The device is working. Comments are like this. The power amplifier at 4 ohm load and half volume works fine. At volume 3/4, it starts to warm up noticeably. Therefore, for normal operation, it is recommended to stick heat sinks on the microcircuit and on the board under the microcircuit. The FM receiver has low sensitivity. It picks up radio carriers but does not play sound. Therefore, if the radio station is 15-20 kilometers away, then it may not be possible to catch it. When connected to an FM generator, a signal is detected, which means that in principle the receiver is working. Distortion is low enough to play music normally at home and in the car. Here, much depends on the quality of the acoustics used. Having your own built-in power amplifier is an undeniable advantage. I tested three varieties of similar devices. The first two did not have built-in power amplifiers. But FM receivers in all three cases had low sensitivity and in my area they did not receive radio stations. Increasing the size of the antenna, using a quarter-wave pin or a directional antenna does not solve the problem. And the car receiver accepts. So these are the features of the receiver chip used.
