ExperimentPurpose

1. There are many kinds of electronic components in the kit: resistance, capacitance, inductance coil, diode, integrated circuit, headphone socket, button and other electronic components, and many kinds of basic components.

2. Learn electronic circuits.

3. Cultivate practical ability.

4. Use epoxy PCB boards especially suitable for student welding.

Product Advantages

For electronics hobbyists or students in electronics class, this FM radio kit optimizes the arrangement of components for beginners, especially for students or hobbyists using welding tools for the first time. This kit is easy to install and make, and the success rate is very high! We know its performance because it has been used in many schools. This kit is not only for welding and assembling, but also for adjusting the coil and winding the coil by yourself. It is more fun, which is better than other simple assembly kits. The advantages of using earphones are mainly concerned with the noise of students in class!

Kit fabrication requires appropriate electronic skills and hands-on skills, please make sure you can complete the production! All the kits we provide are high quality components and have passed the implementation. The tin on the components and PCB clippers cannot be returned or replaced. We do not accept any return or bad comments due to unsuccessful installation! Like the poor review of buyers please detour, the shop reserves the right to choose buyers!

Method of use

FM radio has the advantages of rich programs, good sound quality, etc… all over the broadcasting of their own FM radio stations. The suite FM pocket computer radio USES special integrated block, double row 16 feet flat pack, working voltage is 1.8~3.6V, the circuit contains an FM radio from the antenna to the discriminator output audio signal of all functions, also has the search tuned circuit, signal detection circuit, noise circuit and partial frequency locking ring FLL frequently in compression circuit. The intermediate frequency of the circuit is designed as 70KHZ. The peripheral circuit does not use the intermediate frequency transformer, and the selection of the intermediate frequency is completed by the RC intermediate frequency filter inside the circuit. It uses electrical tuning buttons (SEEK+, SEEK-), volume control buttons (VOL+, Vol-) and power on/off buttons (PW) like a digitally tuned radio. After the circuit is connected to the power supply, press the power switch button, the circuit will start to work, press SEEK+ to search the high-end frequency or SEEK-to search the radio station tothe low-end frequency, automatically search the radio signal, tuning automatically stop, if then press the search button, the circuit will continue to search the radio station. The frequency range is 76~108MHZ. It can receive both general FM station and school campus radio station.

Frequency range: FM 76~108MHZ wider than the common 88~108MHZ range!

Welding sequence: weld patch components first, then: 1. Resistance 2. Inductance 3. Capacitors 4. Diode 5. Buttons 6. Headphone jack and switch
