?RDA5807 DIY KITKit Purpose:1, Suite variety of electronic components: a plurality of electronic components, resistors, capacitors, inductors, diodes, integrated circuits, headphone jack, ons, etc., many kinds of basic components.2, learning electronics.3, practical ability.4, is particularly suitable for use epoxy PCB welding students use rather than for general use paper-based board!Frequency range: FM 76-108MHzAdvantages:Electronic enthusiasts or electronic production of electronic student classes, in particular to optimize the arrangement of the elements according to the beginner, this package easy to manufacture and install a high success rate! As it has been used in many schools, so we know its performance. This kit is not just welding assembly, as well as adjust their own hands and the coiled coil, more fun, this is better than the other simply assembly kit. The main advantage of using the headset also takes into account the student's classroom noise!Features and use:FM radio program has a rich, good sound quality, etc.All over launch its own FM radio station. 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 offset 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 ons (SEEK +, SEEK-), in addition to the volume control ons (VOL +, VOL-) and the power on (PW). After the circuit is powered on, press the power on, the circuit starts to work, press SEEK + to search for high-frequency or low-end press SEEK- radio frequency search, automatic search for radio signals, tuning automatically stops, then click on the Search on if The circuit continues to search for radio stations. Frequency range is 76-108MHZ. Both receive Universal FM FM station can be received school campus radio station.?GS1299 DIY KITPCB board size: 5.5CM*3.7CMShell size: 6.7CM*5.1CM*1.9CMWorking voltage: 3.7V-4.2VBattery capacity: 250mahSupport Headphones: In-ear HeadphonesTo make this kit, you may need the following tools:Soldering iron Multimeter Solder wire Diagonal pliers Screwdriver TweezersA good stereo radio kit!
