Purpose of the kit experiment:
1. There are many types of electronic components in the kit: there are resistors, capacitors, inductors, diodes, integrated circuits, earphone sockets, buttons and many other electronic components. There are many types of basic components.
2. Learn electronic circuits.
3. Cultivate hands-on ability.
4. Use epoxy resin PCBs that are especially suitable for student welding, instead of general paper-based circuit boards!

Frequency range: FM76~108MHZ is wider than the common 88~108MHZ range!

Advantages of use in school training : It is used for electronic production by electronic enthusiasts or students in electronic classes. This FM radio kit is specially optimized for beginners, especially students or enthusiasts who are using welding tools for the first time. Arranged, this kit is easy to install and have a very high success rate! We know how it performs because it has been used in many schools. This kit is not only welding and assembling, but also adjusting and winding the coils by yourself, which is more fun. This is also better than other simple assembly kits. The advantages of using headphones mainly take into account the students’ classroom noise problem !

( Note:

1. Products marked “DIY Kit” in the product title are all parts and need to be welded and assembled by yourself.

2. Kit production requires corresponding electronic skills and hands-on ability, please make sure you can complete the production! The kits we provide are all high-quality components and have all been implemented. The components and PCB clippings cannot be returned or exchanged after being tinned. We do not accept returns or negative reviews due to unsuccessful installation! Buyers who like negative reviews please avoid it, our store reserves the right to choose buyers! )

Features and usage : FM radio has the advantages of rich programs and good sound quality. Every country has its own FM radio station. This set of FM pocket computer station selection radio adopts a special integrated block, a 16-pin dual-row flat package, and the operating voltage is 1.8~3.6V. This circuit includes all the functions of the FM radio from antenna reception to frequency discrimination and output audio signals. It also has Search for tuning circuits, signal detection circuits, squelch circuits, and frequency locked loop FLL circuits that compress IF offsets. The IF frequency of the circuit is designed to be 70KHZ. The peripheral circuit does not require an IF transformer. The IF selection is completed by the RC IF filter inside the circuit. This machine uses electric tuning buttons (SEEK+, SEEK-) like a digital tuning radio, as well as volume control buttons (VOL+, VOL-) and a power switch button (PW). After the circuit is powered on, press the power switch button and the circuit will start working. Press SEEK+ to search for high-end frequencies or press SEEK- to search for low-end frequencies. The radio signal will be automatically searched and tuning will stop automatically. If you press the search button again , the circuit continues to search for radio stations. The frequency range is 76~108MHZ. It can receive both general FM stations and school campus radio stations.

Welding sequence : first weld the chip components, then: 1. Resistor 2. Inductor 3. Capacitor 4. Diode 5. Button 6. Headphone socket and switch
