SSY Components + PCB Board + 2 Battery Boxes KT0837 FM Radio Kit Electronic DIY Production Kit Training Welding Parts

Description  This circuit is tailor made according to the characteristics of KT0837 The circuit selection and volume are controlled in both directions In addition the power supply is directly connected to the power supply terminal pin 1 of the chip and the switch on pin 10 is used to control the standby state When in standby the circuit consumes only a few microamperes and has a radio memory function That is when the IC works again it will stop at the frequency it received last time It shows that this circuit is not suitable for speaker playback and is most suitable for headphones because the headphone cable can be used as an antenna  Specification  Voltage DC3VBoard size 35mm x 53mm Component nameQuantity Component nameQuantity Resistance 10K1At the touch of a button4Color ring inductor 1uH2Crystal 32 768K1Ceramic capacitor 20pF13F07 Headphone Holder1Ceramic capacitor 1011switch1Ceramic capacitor 1041Battery box1Electrolytic capacitor 33uF1PCB board1 Package includes  1 x Training Welding Parts
