DIY Electronic Kits Wireless Stereo FM Radio Receiver Module PCB 76MHz-108MHz DC 1.8V-3.6V

The kit FM scan radio pocket computers using special blocks, 16-pin dual flat package, the working voltage of 1.8-3.6V, the circuit includes a FM radio receiver from antenna to the frequency discriminator output audio signals of all the features, it also has search tuning circuit, the signal detection circuit, a mute circuit and compression frequency 0ffset of the frequency-locked loop FLL circuit. IF frequency of the circuit is designed to 70KHz, peripheral circuits without intermediate frequency transformer, wherein the frequency is selected by an internal RC circuit IF filter to complete. Aircraft such as digital radio tuner that uses electrical tuning buttons (KEY/SEEK+, KEY/SEEK-), in addition to the volume control buttons (VOL+, VOL-) and the power button (PW). After the circuit is powered on, press the power button, the circuit starts to work, press KEY/SEEK+ to search for high-frequency or low-end press KEY/SEEK- radio frequency search, automatic search for radio signals, tuning automatically stops, then click on the Search button if The circuit continues to search for radio stations. Frequency range is 76-108MHz.
