76-108MHz DC 1.8V-3.6V FM Radio Audio Receiver Module PCB Learning Training DIY Assembly Electronic KitsFeature:Electronic products for electronics enthusiasts or student electronic manufacturing. The layout of the elements is optimized especially for beginners. This kit is simple to make and has a high installation success rate! This kit is more fun than soldering and installing coils with do-it-yourself tuning and coiling, which is better than other kits that are easy to install. The main benefit of using headphones is also taking into account the noise in the student's classroom! FM radio programs have the advantages of richness and good sound quality. He runs his own FM radio station everywhere. This kit uses a dedicated module for FM radio bay computers, a 16-pin dual flat pack, and runs on 1.8-3.6V. The circuit includes all the functions of an FM radio receiver from an antenna to a frequency discriminator to the output of the audio signal. It also has a search tuning circuit, a signal sensing circuit, a mute circuit, and a frequency-locked loop FLL circuit that compresses the frequency shift. The intermediate frequency of this circuit is to be 70KHZ, and the circuit circuit does not need an intermediate frequency transformer, and its frequency selection is supplemented by the indirect frequency filtering of the internal RC circuit. Except for the volume control buttons (VOL+, VOL-) and the power button (PW). After the circuit is turned on, press the power button, the circuit starts to work, press SEEK+ to search for high frequency or low end, press SEEK- to search for radio frequency, automatic search for radio signals, tuning stops automatically, Then click the search button if the circuit is still searching for superior radio stations. The frequency range is 76-108MHZ. It can receive both general FM FM radio stations and school campus radio stations. Specification:Material: Electronic ComponentsModule Size: About 100x7 0mm/3.94x2.76 inchApplication:1. Supporting various electronic components: resistors, capacitors, inductors, diodes, integrated circuits, headphone jacks, buttons, etc., various core components.2. Learn electronics.3. Practical skill.4. It is especially suitable for students who use epoxy soldering instead of commonly used paper substrates! Frequency Range: FM 76-108MHzNote:Due to the different monitor and light effect, the actual color of the item may be slightly different from the color showed on the pictures.
