Radio Assembly kit FM Frequency Modulation Circuit Board Production Microcontroller DIY Electronic Production Welding Practice Parts, Voltage: 5V/3V Dual Power Supply. (Without Shell)

Description

• 1. Dual voltage power supply design (5V/3V): Advantages: Flexible adaptation to different power supply scenarios (such as computer USB power supply or mobile power bank). 3V mode has lower power consumption and is suitable for battery life requirements.
• 2. 87-108MHz full frequency FM reception: covering the standard FM broadcasting frequency band, it can receive campus radio and local radio stations. Sensitivity depends on antenna design (kits may require external wires as antennas).
• 3. Function: With shell: The metal shell suppresses electromagnetic interference (especially motor and switch power supply noise) and improves reception stability. Shell free: Suitable for rapid detection of circuits during debugging, or as an open electronic artwork display.
• 4. Application scenario: Drive small speakers or headphones for output. Power limitation is suitable for classroom experiments to avoid high-frequency noise pollution. Scalability: The volume can be increased through an external amplifier module (impedance matching is required).
• 5. Tip: The high-frequency circuit (local oscillator part) is sensitive to layout, and beginners may not be able to receive it due to virtual soldering. Suggest debugging the low-frequency module (audio amplifier) first, and then gradually verifying the RF part.
