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.
