Listed at 5.99 USD. ☆ Welcome☆ to ☆ my ☆ shop ☆ About this item :This is a DIY mini FM stereo radio receiver kit. (SMT soldering skill needed) It comes with many electronic components and a high quality PCB board. This kit would be great for those beginners of both electronic and soldering while building something useful and having fun.FM radio assemblingPurposes of DIY Kits1. Train practical ability.2. Learning electronic circuit.3. The Kit contain vary electronic components：resistors, capacitors, inductors, diodes, integrated circuits, headphone jack, buttons, etc., base component，Users can be use it by adding a stereo headset and two AA batteries.Frequency Range： range 76~108MHZ Features and usage：FM radio with a program rich, good sound quality, etc., all over your FM radio station began broadcasting.The kit FM scan radio pocket computers by using HEX3653 blocks, 16-pin dual flat package, the working voltage of 1.8 ~ 3.6V, the circuit includes FM radio receiver from the antenna to the frequency discriminator output audio signals all the features, it also has search tuning circuit, the signal detection circuit, mute circuit and frequently biased compression frequency-locked loop FLL circuit.IF frequency 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.The machine, like digital radio tuner that uses electrical tuning buttons (SEEK +, SEEK-), in addition to the volume control buttons (VOL +, VOL-) and power switch button (PSW). After the circuit is powered, press the power button, the circuit began to work, press SEEK + to the high frequency of search or search by SEEK- low-end radio frequency, automatically search for radio signals, tuning automatically stops, if then press the Search button The circuit continues to search for radio stations.Frequency range is 76 ~ 108MHZ. Both receive Universal FM radio station can be received school campus radio station. When receiving effect is reduced or noise is large than before, replace the battery! Insufficient battery power or voltage, noise will be larger and difficult search for a station.Welding sequence：First solder SMD components(as short video, need careful, pay attention to polarity)Then solder 1. Resistor -->2. Inductor --->3. Capacitance -->4. diodes, transistors -->5. Key-->6. headphone socket and switch(Please note that when welding electrolytic capacitors C1, C2 of polarity, LED light-emitting diode polarity, Switching diodes D1, D2 polarity) welding LED Note need fast, not stay a long time, otherwise it will damage LED! )Electronic kit (complete set of spare parts) for electronic lover assembled by themselves, learn electronic knowledge, experience hands-on fun, enjoy the fun of success, and share the fun with teachers, students, relatives and friends.Button ：（1）PSW ----power on/off switch （2）VOL- voice decrease （3）VOL+ voice increase （4）SEEK- seek the below-frequency channel （5）SEEK+ seek the up-frequency channelThis electronic kit applicationCollege student teaching experiment in school, is a required course for electronic professional, communication technology, informationtechnology, mechanical and electrical automation control good material (material). Students also carry out a second classroom teaching activities.Package include :- All components to build this kit(not include battery, the airmail ban it.)- 1pc AA battery holder Shipping> We ship to worldwide.> Orders processed within 24-48 hours after payment verification.> We only ship to confirmed Paypal addresses.
