HEX3653 FM Radio Receiver Module D.I.Y. Kit
This FM receiver is a D.I.Y. kit that requires soldering through-hole and surface mount components on a double-sided printed circuit board. It is designed for users with advanced soldering tools and skills. You must solder the IC pins on the top surface and the rest of the components’ leads on the bottom side of the board. The assembly process should take anywhere between 30 minutes to an hour. This kit should help you to practice your hands-on skills including your soldering techniques.
The module is based on a HEX3653 IC which is essentially an FM radio chip that can receive modulated FM signals with a frequency range of 76 to 108MHz. The integrated circuit of this module will allow you to increase/decrease the volume, seek channels on the FM band and use an external antenna if needed. The filters will separate the desired radio frequency signal from all other signals picked up by the antenna. The amplifier is used to increase the power of the signal for demodulation process of the FM composite signal. For a more in-depth description of how this FM receiver works refer to section 5 (page 5).
Required Input Voltage: 2x AA 1.5V Batteries (≈ 3V)
